Sensing and Telemetry News
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.
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 KGF line of capacitive level controllers, which complies with NAMUR and DIN EN 60947-5-6 standards, are well suited to particularly demanding tasks. For example, the sensors are able to monitor the fill level of viscous paint – this often causes problems with other devices since the medium sticks to the sensor and is highly conductive because it contains metal pigments.High temperature inductive proximity sensors
