The MT32 Mini-Telemetry is a very small and flexible telemetry system for rotating, mobile and stationary applications. Each sensor module is equipped with signal conditioning, anti-aliasing filter, analog-to-digital converter and a digital output.

Up to 32 of these modules can be controlled by one encoder (multiplexer with PCM output) module. Due to this concept it is possible to install the acquisition modules close to the sensors in order to have short analog sensor lines. This avoids undesired coupling of disturbances resulting in noisy signals. The interference insensitive digital outputs can lead over longer distances of up to 1 m to the encoder module.

The encoder output is a PCM bit stream signal which can be modulated for radio transmission over distances of up to 10 m. Suitable for wireless data transmission rates from 40 kbit/s up to 2560 kbit/s.
