Installation of the MT32 Modules
Attach all the MT32 modules on the final
position on the shaft using the “tesa® PowerStrips® Mini”.
Fix all MT32 modules with at least 10 layers of
the special mounting tape around the shaft.
According to the shafts RPM and diameter it’s
particularly paid attention to safe mounting of
the components. The manufacturer doesn’t
accept liability for damages, which results from
not sufficiently attachment of the individual
components. The provided cable harness and
the tape are only for test purposes, in order to
test the electrical function of the units in the idle
state of the shaft.
During the rotation test appropriate safety tools
are to be attached.
The entire installation may be used only by
authorized persons. By using tape for the
attachment, it has to be used in the direction of
rotation of the shaft and the end has to be
secured against removing. Only non-elastic
tapes with high tensile strength have to be used
for pre-fixing. Add. use horse clamps for final
fixing!!
The individual components are to be distributed
in such a way on the shaft that imbalances will
avoid.
hose clamps
All cable connections soldered!
The user has to pay attention to connect the
wires to the correct pins - the units have no
reverse-connect protection!

MT32 to consider at assembling
According to the shafts RPM and diameter is particularly paid attention to safe mounting of the

are only for test purposes, in order to test the electrical function of the units in the idle state of

The individual components are to be distributed in such a way on the shaft that imbalances
will avoid. All wire connections should be soldered. The user has to pay attention to the
correct polarity of the cables – the units have no reverse-connect protection!
Transmitting antennas and sensors should not be installed next to each other. To ensure a
reliable function, the receiving antenna should be positioned in such a way that all LEDs lights
up at the field level display on the receiver.
Don’t plug any modules if Power is ON!!! First power OFF!!

Installation of the radio transmitter on a shaft
Cable Red = +5V
Cable Black = GND (Ground)
Cable Brown = PCM In
Cable White = Wire antenna
All cable connections should be soldered.
Mount the cable antenna exactly one winding
around the shaft and fix all with 3 windings
mounting tape – finish!
The cable antenna can extend or shorten
depending upon requires! (isolate the solder
connection, if you extend the wire antenna
cable!)
This coaxial adapter (MT32-40k-Tx-TNC-adapter)
makes it possible to connect a 433 MHz
antenna with TNC connector for point to point
applications. (option)
433 MHz transmitting antenna 0dB

With 45MHz carrier is only 1x winding necessary!
Attach for electromagnetic insulation “Ferrite Tape” 2 x one layer around the shaft.
Make transmitting coil with 1x winding and twisted the
end of wire. Use CUL 1mm wire
(CUL = Enamelled copper wire)
Fixed it with 3 layers mounting tape
Extend the CUL wire flexible 0.14-0.25mm wire
(to decouple the inflexible 1mm wire!)
Twisted also the flexible wire and solder it on the MT32IND-Tx (isolate all solder points with shrink tubing)

To avoid transmitting problems, the transmitter module must be close the transmitting antenna!
The cables (PCM/GND/+5V) between MT32-IND-TX 45MHz and ENC8/16 can be 1000mm long!
CAUTION:
If you want to install also an inductive power coil close to the data coil, the minimal
distance must be <10mm! (distance between IND-PWR coil to IND-DATA coil)

with two 45MHz carrier pickup heads at large shafts (>500mm)
At shaft diameter lager then >500mm diameter, you
can get zero points in the 45MHz antenna. To avoid
transmitting loss, we recommend using a second
pickup head! The distance between two pickup heads
must be 45° to 90°.
On the MT-DECODER (receiver) you can see the
yellow status LED of Pickup. At good magnetic level,
the LED is bright and Pickup is active.

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 5m to the encoder module. The encode r output is a
PCM bit stream signal which can be modulated for emission by a transmitter module.
To support a wide range of applications there are different HF- transmitter types available. This includes different distances (short and long),
transmission rates (40, 320, 640, 1280 or 2560kbit/s). Please send us an exactly description of your application with a simpl e block diagram.
This ensures to provide you a proposal for an optimal solution.
The supply voltage for the transmitting part is 5V DC. It can be generated by batteries, inductive or mains power supplies (d epends on
application). Optional it’s also possible to combine all signal acquisition modules, encoder, transmitter and batteries in a small housing as a
compact ready-to-use telemetry system (CT8-16). For strain gage applications the offset can compensated by potentiometer on the
acquisition module or optional by auto-zeroing via a micro switch on the encoder simultaneously for all modules. The calibration settings are
not affected during power off. The receiver station output the signals in a ± 5V full scale range via BNC connectors. It will powered with 1030V DC or optional by an external mains power supply with 110-230V AC.

Safety notes for inductive powering
 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.

Inductive power supply
Installation of coil for inductive powering on shaft
Attach for electromagnetic isolation “Ferrite Tape” 2x parallel and
1x in the middle over two layer around the shaft
Strip the isolation from the end
of the wire with a skinning tool or
head up you soldering iron over
450°C to burn off the insulation
from the wire!
Make power coil with 3-18 windings for 1000-20mm diameter (see diagram) and twisted the end of wire.
Use 0.63…1.00 mm (1.00mm for diameter of 200-1000mm) CUL wire (Enamelled copper wire)

Solder the end of the pins on the AC IN of the
IND-PWR module and isolate all solder points with shrink tubing
Fix all with 5 lagers mounting tape!
Note: “The inductive load of the MT32- IND-PWR and
the capacitor in the Power Head must be in resonance
to get the optimal transmission. The inductive load of
the shaft depends of diameters, material and number of
windings!
Control the output voltage and move the power-head in
the max distance to the coil.
The output voltage must be 5V
See also status LED
LED ON = right windings and good distance between
head and coil
LED very low blinking = too less windings of IND-Coil or
too large distance between head and coil!
LED fast blinking = too much windings (OVER POWER
at IND-Coil) reduce windings or module go hot and
switch OFF
The pins “Coil” are the AC power input from the coil. On
the pins “+5V and “GND“ you get a stabilized output
voltage of 5V DC.
The max. load current on the DC output is
max. 1000mA.
The IND-PWR converter will use instead battery pack!
Never use any battery together with the IndPwr!
5V DC OUT
max. 1000mA
You should mount the power head at a fixed location
that it’s as free as possible from strong vibration
influences.
AC IN
The center of the coil should be in the same horizontal
position as the center of the power head. The distance
is optimal in the range between 5 and 10mm. (depends
of shaft and current consumption)
