Sensing and Telemetry News
Laser displacement sensor
The LDS 72 is a A new type of laser displacement sensor that 
provides a very high resolution with ranges 5 to 600 mm.
Improved 14 it RTSC at 1500 Hz as well as intelligent image
analysis – peak & threshold selection are available. Analogue scaling with easy teach-in is now first time usable in this economic version
Separate amplifier unit for flow measurement
There is now available a separate amplifier unit to work with the 
versatile SDI 853 type inline flow meters with an impulse output, which enables remote meter reading and programming of switching points. This configuration allows users to fit sensors directly into pipes even in poorly accessible places without compromising on control and functionality.
Telemetry that makes sense
The Metron2 telemetry unit is affordable, flexible and easy to use. It suits a wide range of applications for remote data logging and alarming, including network montoring in the water industry, tank level monitoring in the fuel distribution and chemical industries, discharge and emissions monitoring for environmental purposes as well as general alarming for industrial reporting and security.
MCERTS Telemetry
The use of telemetry can help comply with MCERTS. MCERTS is 
the Environment Agency's certification scheme for monitoring. It plays a key role in operator self monitoring by helping to give the EA confidence that monitoring data meets its requirements.
MCERTS was initially applied to air emission monitoring but has been successfully extended to water and other liquid discharges.
Tax Strip detection on Cigarette Boxes
We have available a colour sensor that is ideal for Tax Strip detection on Cigarette Boxes. The LT1-STB incorporates a long 
lasting LED light source which is projected onto the tax strip using a fibre optic cable.
The received light is separated to RGB and transfered into XYZ, L*a*b or L*u*v. The colour sensor can be interrogated via RS232 colorCONTROL LT/B software.
Colour monitor for testing LED's
Tthe ColorControl MFA is an colour recognition system that is 
capable of monitoring and classifying the colour, intensity and function of LEDs and self- luminous systems at up to 100 measuring stations simultaneously.
The LEDs to be tested are assigned to a test matrix using light guides (up to 2 meters is possible) and a mounting adapter looks after the positioning.
Stainless Steel Proximity Sensor
Stainless steel proximity sensors with non stick coating make them cinder resistant. The
robust stainless steel IGV sensors are coated with a special PTFE coating which makes the proximity switches adhesion-resistant and especially easy to clean. The coating also won’t be damaged by harsher mechanical cleaning processes.
Magnetic Flowmeter
The SDI 852 / SDI 853 type Electromagnetic flowmeters allow
users to continuously monitor flow rates of many conductive media. The devices now feature a new, optional impulse output. Each single impulse corresponds to a defined flow rate. Just like their predecessor models, the new sensors can also be fitted with a PNP or an analog output.
Proximity switches for food
The IGVW range are tightly sealed proximity switches for the
food industry as they are capable of withstanding extreme climatic conditions. The 100% stainless steel IGVW proximity switches are manufactured from one piece and designed to be climatic-proofed so they can withstand even the greatest temperature fluctuations. The high standards of hygiene in the food industry demand a proximity sensor of the highest strength. Stainless steel proximity sensors can also be used in hygienically demanding applications requiring frequent cleaning cycles. Thanks to their seamless finish and specially matched combination of materials they also withstand aggressive cleaning agents, acids and caustic materials and are resistant to pressure cleaning.
Heavy duty in line flow and temperature controller
The new inline sensor for flow and temperature can control heavy
flows up to 100 l/min. The model complements our existing series of space-saving one-device flow sensors for monitoring flow rates and medium temperatures. The flow meter is designed for monitoring water flows. Features include one analog output (4…20 mA) for flow, one analog output for temperature, and a three-digit digital display. Users can easily program flow rate adjustment and averaging. Current readings and programmed parameters can be accessed anytime.
Laser Distance Sensor
Our new laser distance sensor, LDS 72, has high-end 
features at an economical price. It has a measurement frequency of 1500 Hz, 7 ranges, peak elimination software included for difficult measurement peaks and on the rear there is a teach function for learning the real measurement range between two points at full resolution.
Powelectrics offer a wide range of sensors for automation including laser distance sensors, proximity sensors, colour sensors and vision systems.
IP68 Proximity switches
We are now able to offer additional IP68 proximity switches. The renowned Fraunhofer Institute in Germany has tested the Contrinex Series 700 and confirmed that both cable and connector versions of sizes M12, M18 and M30 meet the requirements of IP68 as well as IP69K. This means that sizes M12 to M30 can be employed under water for a certain time and that they resist cleaning by means of high-pressure water jets.
Shockproof proximity switches
The IGV series of inductive proximity switches are made 
from stainless steel and manufactured from one piece. The sensors are highly shock-proof: they easily resist more than ten blows with an impact of eight joules each. One such blow corresponds to a 1 kg weight dropped onto the sensor from a height of 80 cm. They also withstand vibrations, metal cuttings and abrasive media as well as aggressive cooling liquids and lubricants, which makes them ideally suited for use in extremely rugged industrial environments.
Vision system with OCR
Optical Character Recognition (OCR) is a popular inspection task for industrial Machine Vision systems, e.g. for presence or content checking of serial numbers, use-best-before-dates, or component markings, use-best-before-dates, or component markings. With the new PV530, the successful and industrially proven, high-speed Imagechecker PV500 has been expanded to include OCR.
Proximity sensors for the food industry
Contrinex has developed a range of rugged inductive 
proximity sensors that has been specifically designed for dealing with the hazardous environments found in the food industry. Although the food handling process itself does not always present an aggressive environment, the cleaning and wash-down routines required to meet hygiene standards usually involve caustic chemicals that can cause severe damage to control sensors.
When a production line is stopped due to failure the in-process products often have to be scrapped and, in many cases, the line has to undergo a time consuming cleaning routine before it can be re-started. In addition to being extremely expensive, these delays put pressure on production managers to make up quota targets and deadlines after repairs are completed.
Inductive proximity switch
Inductive proximity switch with an extended temperature
range - the IDST and INST proximity switches are ideal for use in applications with high temperatures and rugged environments, such as steel plants. The proximity sensors are suitable for a temperature range from -25 to +120 °C. They are EMC resistant beyond the requirements of relevant norms, and withstand even interference spectra generated by frequency inverters.
Inductive all metal proximity switches
Suitable for the detection of all metals the IGB and IDB inductive
proximity switches ensure a constant switching distance. Available as M30 x 1.5 models, IGB sensors provide a 10 or 20 mm switching distance, while IDB sensors which are available with an 80 or 160 mm diameter have a 70 or 150 mm switching distances.
Contrast Sensor
This contrast senosr allows you to increase process
throughput with high-speed, accurate and reliable contrast differentiation. The new KS30 contrast sensor combines small 3mm spot size and 40 kHz fast response to achieve high-speed contrast differentiation of both neutral and colour targets. The white light LED allows accurate detection of a wide range of colours against any background. Two seven-segment displays provide a visual representation of the relative intensity from 00 to 50. Two gain settings and three LED intensity settings provide for flexible operation over a wide range of conditions. The small spot size allows the resolution necessary to achieve accurate timing and position measurements.
Inductive proximity switches meet increased requirements
The new IGM line of inductive proximity switches are suitable for
installation in rugged industrial environments which would normally cause problems for standard inductive sensors. IGM sensors have been specially optimized to ensure EM compatibility and withstand interference caused by frequency inverters.
Ethernet Radio Modem
The ERM4024E is a 802.11b/g compliant Ethernet 
radio modem operating in the license-free 2.4GHz band. Capable of transmitting data up to 54Mbits/s over distances in excess of 1km (terrain and antenna dependant), the ERM4024E is a reliable and secure unit that provides high-speed wireless Ethernet connectivity across a broad range of applications in the utilities, process control, private and manufacturing industries. It can connect to a range of Ethernet-enabled devices such as PLCs, HMIs, DCS, data acquisition, video and PCs.
The ERM4024E is suitable for both long and short-range applications. A repeater function also helps to increase the wireless range even further.
Diffuse sensors with analog output
These new rectangular photoelectric diffuse sensors with analog output from Contrinex are characterized by their sensing range from 10 to 100 mm, coupled with excellent temperature stability and outstanding repeat accuracy. The sensing range is independent of the target color or surface structure. In addition, since intermediate digitalization has been dispensed with, the sensors feature a good resolution (see datasheet).
The use of analog sensor technology permits the realization of numerous applications. For instance, the finely adjusted approach to end-point positions at minimum cost, the realization of several switch points with a single device or the monitoring of shaft concentricity. In addition, with a bandwidth of 500 Hz, the sensors also have a voltage output as well as a current output, which gives users great flexibility. These devices are fully potted, equipped with glass windows and comply with the degree of protection IP 67.
Sensor applications on chewing gum machines
One of the world’s most famous manufacturers of chewing gum recently built and set up a large factory in Poland. It is one of the most advanced food processing plants in Europe.When the new production machines came out of warranty spare sensors were required and the local Contrinex affiliate became involved. All of the machines were fitted throughout out with Banner products however availability and reliability of the Banner sensors was an issue. Alternative Contrinex inductive sensors with longer sensing distances were used initially to resolve some of the machine problems.
When that worked out to the 100% satisfaction of the customer Contrinex got increasingly involved where other key problematic problems in the production were concerned. A steady demand for one specific Banner optical fiber had been noticed and so Contrinex asked the clever question, why?
Laser sensors
Compared to conventional LED diffuse sensors, laser
sensors feature improved accuracy. As a result, the switch point of these new devices can be accurately set at any point within the whole setting range of 40 ... 250 mm or 60 ... 600 mm. The narrowly focused laser beam permits the detection of smallest objects (down to 0.1 mm). The diffuse sensors are built into M18 stainless-steel housings and offer long operating distances of 250 mm or 600 mm as well as high switching frequencies of 5 kHz or 1 kHz.
Analogue Optical Sensors
These new analogue optical sensors in size 30 x 30 x 15
mm are characterized by their large sensing range from 10 to 100 mm, excellent temperature stability and outstanding repeat accuracy. The sensing range is independent of the color or surface structure of the object to be detected. In addition, since intermediate digitalization has been dispensed with, resolution of these devices is virtually unlimited.
Safety Light Curtains
Safety light curtains are used wherever risks cannot be
eliminated through machine design. A person or any part of the body entering a danger zone is detected by the light curtain, leading to immediate machine stoppage. Safety light curtains consist of a sender and a receiver unit that demarcate the protection zone between them.
Two-wire proximity sensors save on installation and running costs
Using proximity sensors in large production plants such
as dairies, breweries and food processing and automotive manufacturing plants can present major technical issues resulting from long cable runs and, because cable prices have quadrupled over the past five years, there are also major cost issues. New, high-performance, two-wire DC proximity sensors reduce the amount of cable and number of connection points required in machine design by 33% compared with conventional three-wire products thus producing major cost savings. Another advantage with two-wire products is that the same sensor can be arranged in either ‘normally open’ or ‘normally closed’ configuration when connecting the control load in-line with the positive lead and so NPN and PNP versions are not required as they are with three-wire devices. This can significantly reduce the number of different sensors that customers need to stock thus reducing inventory cost.
UV selective fibre optic amplifier
A fibre optic amplifier for use on glass and flexi-glass 
applications. Normal light barriers cannot be used to detect glass plates because the red or IR light will pass striight through. By using wavelengths shorter than 320 nm the glass will not be transparent and the glass between the transmitter and the receiver will switch the signal.
With a range of 1 to 20mm (increases to 100mm in through beam mode) the unit has switched or analogue outputs.
Applications include glass detection, glass sheet postioning and stop postion for glass sheets as well as compact discs.
The sensors will detect glass, quartz glass, glass for windows, CD's and Plexiglass. They will detect a glass sheet as long as it's thicker thn 0.1 nm.

High temperature proximity sensor
Powelectrics are pleased to introduce to you a new range 
of high temperature inductive proximity switches that have been designed specifically for use in demanding conditions and will reduce costly downtime.
Many manufacturing processes such as furnaces, steel plants, casting machines, engine control, foundries, heat treatment plants, plastic moulding machines, food processing and cooking and baking lines run at temperatures well above 70°C at which most conventional feedback sensors begin to malfunction and fail.
Remote Monitoring System
A remote monitoring system, or at telemetry system, is the remote measurement and collection of data, such as meter reading, tank level monitoring or environmental monitoring.
Telemetry is typically used to gather data from distant, inaccessible locations, or when data collection would be dangerous or difficult for a variety of reasons.
Powelectrics specialise is the design, supply, installation, commissioning and support of GSM telemetry and radio telemetry systems.
Flow sensors for pressurised and micro flows
Two new flow sensors are available featuring robust 
process connections. Both new types are highly resistant to aggressive media and provide fast reaction times. The SDN 503 model detects flows between 1 and 200 ml/min and withstands pressure up to 10 bar.
The SDN 504 DYN model is suitable for micro flow pulses from 0.02 ml/min onwards and pressures up to 20 bar. The sensor ensures e.g. the accurate lubrication of metal sheets before stamping or the minimal lubrication of bearings.
Measured values are continuously monitored by the internal electronics which also generate a switching signal should the flow pulses discontinue. The dwell time can be adjusted in a 0.5...10 s range. Moreover, an integrated LED display shows the current flow status.New inline flow controller
There is a new inline flow controller in the SDN 552 series of which features a digital display. Just like in earlier models, characteristics for water-glycol mixtures are pre-programmed in the new sensor. In addition, characteristics for other media, such as emulsions, cooling liquids or lubricants can be freely programmed. The flow sensors work on the thermal transfer principal which means there are no moving parts.
Telemetry helps walk the dogs
When Powelectrics were asked to sponsor a team planning to climb the 4 highest peaks in Scotland, England Wales and Ireland they were only too pleased to help, and it also gave them an opportunity to put some of their telemetry devices to a rather unusual use.
Wooden Spoon is rugby's charity supporting mentally, physically and socially disadvantaged children and young people. Spoon has committed to over £14 million in spending for projects for children and young people. It has organised over 2,000 events and had over 25,000 ties worn by its loyal members and supporters. Hardworking staff and volunteers have achieved all of this since the birth of the charity.
It all began on a fateful day in Dublin in 1983 when England’s Five Nations season ended in disaster with defeat by Ireland leaving them languishing at the bottom of the table.
Magnetic flowmeters
SDI 852 type electromagnetic flowmeters allow users to continuously monitor the flow rates of many conductive media. The devices now feature a new, otional pulse output: each single impulse corresponds to a defined flow rate. Just like the earlier models, the new sensors can also be fitted with a PNP or an analog output.Inductive proximity switches for underwater use
The new IGMO type inductive proximity switchesare especially suited for use in offshore and underwater applications. The units, whose housings are made from PTFE and stainless steel 1.4571, can be permanently installed in depths up to 300 m and withstand pressure up to 30 bar.

Microwaves are transmitted down within the dip stick and upon contact with the medium they are reflected back up. The sensor determines the level within the tank. The units do not need to be adjusted to different media.
2D Barcode reader
The new 2D Barcode reader has a working range of 100mm and a detection window of 48 x 40mm the ELCR 4840 will detect OCR/OCV and barcodes in 360 degrees.
Diffuse laser sensors
This new range of diffuse laser sensors allow cost-effective sensing of small objects. These M18, low cost, high precision diffuse laser sensors designed to solve the problem of detecting small components or features during manufacturing processes. This type of detection has long posed difficulties for manufacturing engineers and compact, focussed beam sensors or accurately set miniature fibre optics are often used. However, both these methods require that the sensors are situated close to the target and in many applications there is insufficient space to implement these arrangements. As a result, vision systems are sometimes the only practical alternative but such systems are highly expensive and require a high level of application knowledge for reliable deployment.Contractor Award for Telemetry
