Long range radio telemetry offers a cost-effective, flexible and practical alternative to hard-wired data logging systems without forfeiting system reliability or security. The use of telemetry does not restrict the type of sensors that can be connected, accuracy of measurements or metering capability. Licence exempt UHF frequencies are used and sensors can be located almost anywhere


Eltek GenII monitoring systems provide data logging and alarm generation for a very wide range of applications. Systems are already installed in museums, laboratories, storage and warehousing facilities, pharmaceutical, production, and domestic premises – just about any environment where accurate and reliable data is essential for monitoring, manufacturing, research or audit purposes.

Now with 250 sensor capability, 125 transmitter capability, 250,000 readings and built in standby battery. Cost effective, even on occasions when using one transmitter and one sensor only, GenII can be expanded to meet any users requirements. Licence exempt UHF frequencies are used and sensors can be located almost anywhere.
