Modular telemetry for rotating shafts

MTP Telemetry

MTP-STG modular telemetry

Multi-channel telemetry system for rotating applications, fully software programmable with 16 bit resolution

The MTP telemetry is a small and flexible telemetry system for rotating applications. Each sensor module (2-channel) is equipped with signal conditioning, anti-aliasing filters, analog-to-digital converters and a digital output. Up to 32 modules (= 64 channels) can be controlled by one MTP controller 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 25 cm from module to module.

The MTP controller output is a PCM bit stream signal which can be modulated for wireless data transfer over distances of up to 0.1 m with inductive telemetry transmission or up to 10 m with radio telemetry transmission. Suitable for wireless data transmission rates from 312.5 kbit/s up to 5000 kbit/s.
