The Eltek GenII series is a new range of telemetry products providing reliable radio data logging for a wide range of users and applications. Sensors can be located almost anywhere with reliable and secure collection data assured.

Radio Telemetry offers a cost-effective, flexible and practical alternative to hard-wired data logging systems without forfeiting system reliability or security. The GenII telemetry system does not compromise on the range of sensor types that can be connected, measurement accuracy or metering capability. Consistent performance in a range of environments is ensured by using only the very highest quality licence exempt FM low power radio modules.

What is radio telemetry?

What are its advantages over wired or cabled-in systems?

Simply the transfer of information using radio as the bearer.

Wireless systems offer an almost unlimited freedom to site sensors. Information is collected by the sensors and periodically transmitted to the Receiver Logger for PC analysis or real time metering.Transmitting over the Licence-exempt Low Power Radio (LPR) spectrum means no annual licence fee, and the use of standard system modules allows rapid systems design, installation and expansion.

Where is it currently used?

Eltek Support

The Eltek Radio Telemetry System is designed as a total system solution. Existing installations include environmental monitoring, the storage of sensitive chemicals and drugs and the monitoring of manufacturing processes. Customised thermal barriers are available for through-process measurement in extreme temperatures.

Eltek's Technical help line is there to assist from project conception to completion and beyond. A three year warranty is standard.

Guarantee Equipment manufactured by Eltek is guaranteed against faulty materials or workmanship for three years. For repairs carried out under guarantee, no charge is made for labour, materials or return carriage.
