Short description:
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 filters, analog-to-digital converters and a digital output. All
these up to 32 modules will controlled by an encoder (multiplexer with PCM output) module. By this concept it’s possible to
install the acquisition modules close to the sensor to have short connections for the analog sensor lines. This avoids an
undesired coupling of disturbances resulting in noisy signals. The interference insensitive digital outputs then can lead over
wider distances of up to 1m to the encoder module. The encoder output is a PCM bit stream signal which can be modulated
for emission by a transmitter module for a distances of up to 10m. Suitable for wireless data transmission rates of 40kbit/s up
to 2560kbit/s.
