1-channel telemetry for rotating shafts

MT1-PCM

MT1-PCM-telemetry

Digital radio telemetry system for strain gage applications on rotating shafts - Gain and auto zero setting directly from the receiver side!

The MT1-PCM single-channel telemetry system offers the easiest handling for the wireless radio transmission of strain gage signals from rotating shafts.

The dimensions of the encoder (MT1-PCM-STG) are 62 x 27 x 11mm, those of the transmitter (40k-Tx) are 62 x 27 x 11mm (each without connectors). Each module has a weight of about 30g. The encoder/transmitter parts are simply mounted on the rotating shaft with a special fiber reinforced tape and fixed by a steel clamp.

Powering of the transmission part is by battery (6-9V), power consumption 90mA. The digital data transfer between transmitter and receiver uses radio frequency bands of 433MHz or 868MHz, transmitting power is 10mW.
