Rotating telemetry for wheels and rotors


32 channel telemetry for rotating applications like wheels or rotors, high signal bandwidth, 16 bit, software programmable

The CTP32-Rotate is a 32-channel telemetry system for rotating applications with integrated signal conditioning for sensor signals, wireless digital transmission and analog reproduction.


In the encoder/transmitter unit the sensor signals are conditioned, filtered (anti-aliasing) and digitized (16 bit). Simultaneous sampling is provided for all channels. Finally the PCM encoded data is transmitted via radio frequencies to the receiver.

Various configurations of different sensor modules are available incl. signal conditioning for strain gages (STG), thermocouples type K (TH-K), ICP sensors, potentiometer sensors (POT) and also voltage inputs. Mixed configuration available (2-CH-steps).

All sensor modules are software programmable via LAN-Adapter. The LAN-Adapter has an integrated web interface and enables easy access!

The stationary receiver provides 32 +/-10 V analog outputs via Sub-D male socket (option: digital PC interface).

The analog signal bandwidth is 0 - 190 Hz (320 kbit) and up to 0-1500Hz (2500 kbit) for 32 channels. The measurement accuracy is < ±0.2 % (without sensor). The CTP32-Rotate is specified for operational temperatures from -20 °C to +70 °C. The maximum distance between transmitter and receiving antenna is approx. 10 - 20 m (30 - 60 feet) – depending on the application! Mixed configuration available (2-CH-steps).
