Radio connected sensors offer an unrivalled flexibility to create data gathering systems without the encumbrances of wires. Often users have invested heavily in conventional loggers or other data acquisition system. For the first time Eltek's WSR enables users to integrate wireless connected systems to their existing systems, using field proven GenII transmitters and sensors providing accurate measurement without sacrificing reliability or performance. The WSR system is now offered as a system in its own right.
The WSR is a self-contained mains-powered receiver and output unit with built-in batteries providing 48 hours of operation in the event of a mains failure. An LCD is incorporated for real time metering of sensor values. The WSR is suitable for systems which accept 0-5VDC analogue inputs with slowly changing variables – typically measured every 10 seconds. Two models are available with either 8 or 16 inputs/outputs.
Most Eltek GenII transmitters can be used with the WSR (apart from event or pulse transmitters).
