Digital telemetry system for strain gage applications on rotating shafts - Gain and auto zero setting directly from the receiver side!
The TEL1-PCM single-channel telemetry system offers the easiest handling for the wireless transmission of strain gage signals from rotating shafts. The very small encoder (35 x 18 x 12 mm) has a weight of only 13 g. The transmitter (encoder) part is simply mounted on the rotating shaft with a special fiber reinforced tape.
Powering of the transmission part and the digital data transfer between transmitter and receiver is realized inductively.
