Safety notes
•The device should only applied by instructed personnel.
•The power head emits strong magnetic radiation at 30-60 kHz to a distance of 300 mm.
Therefore persons with cardiac pacemakers should not work with this device!
•Magnetic data storage media should be kept in a distance of at least 3m from the power
head to avoid data loss. The same is valid for electromagnetic sensitive parts, devices and
systems.
•Do not place the power head in the switched-on state on metallic objects, because this
results in eddy currents which could overload the device and strong heat up small objects.
Also the probe could be destroyed!
•No metallic objects, other than the disc-type coil, should be located in the air gap of the
power head. The same applies to metallic parts within a radius of up to 50 mm in all
directions.
•Do not use damaged or faulty cables!
•Never touch in the area between shaft and inductive head, the rotating shaft itself or rotor
electronic contacts during operation!
•This is a “Class A” system suitable for operation in a laboratory or industrial environment.
The system can cause electromagnetic interferences when used in residential areas or
environments. In this case the operator is responsible for establishing protective
procedures.

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.
