Sensing and Telemetry News
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.
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.
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.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.
The sensor cable is longitudinally water blocked: even in case of damage to the cable sheath or a complete cut through the cable, water will not intrude into the sensor or the control enclo-sure.
Precise Level Monitoring
The new MFM series of level monitors are ideal for the continuous monitoring of liquids. It allows users to precisely detect fill levels in plastic or metal containers with a maximal measurement error of 10 mm. The level controllers monitor a wide range of liquids, such as water, oil or emulsions.
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

The new KU amplifier for capacitive level controllers allows users to auto-calibrate sensors by simply pushing one button. The calibration includes the medium as well as mounting conditions, thereby preventing incorrect start-up. An LED line on the device serves to confirm correct auto-calibration. A medium exchange merely requires auto-calibration to be started once – the level controller will be ready for operation again after a few seconds.Magnetic Flowmeter
We are please to introduce to our flow sensor range a magnetic flowmeter, the SDI series. These magnetic flow meters are fitted directly into pipes via tube fittings or adapters.Microwave level controllers
The new MFC range of microwave level controllers have a sensor tip which reacts to contact with a medium.
