Short description:
The MTP-NT telemetry is a miniaturized measurement system suitable for sophisticated industrial measurement tasks and rotating
applications. Each 2-channel sensor module is equipped with signal conditioning, anti-aliasing filters, analog-to-digital converters (16 bit)
and a digital communication bus connection. All these up to 128 modules (=256 channels) will be controlled by the MTP-NT-Controller
module via a daisy-
chain system bus (extendable to several meters). 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 undesired interferences in noisy environments. The MTP-NT
Controller outputs a PCM bit stream signal in NRZ format with data rates up to 5000 kbit/s. The inductive transmitter module transfers the
signal over distances of up to 50 mm and the radio transmitter is able to cover ranges of 10m, depends of application.
