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 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. All these up to 32 modules (=64 channels) will controlled by
MTP-Controller 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 25cm module to module. The MTP-Controller output is a PCM bit stream signal which can be
modulated for emission by a transmitter module for distances of up to 0.1 with inductive telemetry transmission or up to 10m with radio telemetry
transmission. Suitable for wireless data transmission rates of 312.5kbit/s up to 5000kbit/s
