Intelligent RFID transponder with monitoring functions for sensor data

June 01, 2015 // By Graham Prophet
Harting has developed its RFID Embedded Transponder (ETB) with a range of extended functions including the ability to monitor and transmit sensor data. An object or component that is equipped with an RFID transponder can determine and wirelessly transfer not only its own ID, but also its current status with the help of connected sensors.

The integrated UHF (ultra high frequency) technology embedded in the transponder acts, in effect, as a direct control system, and allows mobile parts that do not have their own constant energy supply to be monitored comprehensively.

In this passive mode of operation, in which the system on the transponder side functions without an energy source, is a major advantage of UHF-based control systems, the system obtains its energy from the RFID reader device, and powers the RFID transponder via the transmitted radiation - which in Europe lies in the frequency band from 865 to 867 MHz. The transponder can address external sensors and transmit data to the reading device over a range of up to 3m. The device comes in a range of formats optimised for differing application environments.
