4. Description of the measuring system
4.1 Mechanical design
The torque sensor consisting of a main casting
accommodates the shaft, which rotates in bearings. The
shaft ends are free.
On the measuring shaft at the torsion section strain gages
are arranged, as well as electronics with signal amplifier
and A/D converter. In the connection box of the main
casting the stationary electronics for signal shaping are
positioned. The main casting provides various assembly
possibilities (see chapter mechanical installation).

Description of the measuring system
4503B_002-736e-02.22 Page 9
5. Transmission
Transmission of power and data from the torque sensor to
takes place via inductive coupling (telemetry). Frequencies
from the ISM band between 115 … 130 kHz are used for
this purpose.
The feed frequency is PSK modulated for sending data to
the rotor. Depending on the feed frequency, the data rate
can be between 360 ... 406 bit/s.
The ISM band frequency 13,56 MHz is used for receiving
the measurement data. The measurement data are also
transmitted from the torque measuring unit to the torque
evaluation unit via inductive coupling as a PSK modulated
signal, at up to 1,4 MBit/s. In addition to the torque, the
rotor measurement data include the temperature, supply
voltage, and EEPROM (electrically erasable programmable
read-only memory) contents.

7. Electrical connection of torque sensor
7.1 Supply
Excitation of torque sensors Type 4503B... requires a
supply voltage in the range of 11 ... 30 VDC.
The direct voltage is supplied at the 12 pin panel plug at
Pin F (+UB) and A (GND). Power input is <10 W. Galvanic
isolation takes place between the power supply and torque
output in the torque sensor.
7.1.1 Power input in function of excitation voltage

7.6.1 Measuring range selection
If the torque sensor is additionally calibrated in the 2nd
range at the factory, the requested range may be switched
via PIN 1 and via 7 pin connector.
4503B…
Measuring range logic condition voltage level
1:1 PIN1 = 0 UPIN1,7 = 0 ... 2 V
1:5/1:10 PIN1 = 1 UPIN1,7 = 3,5 ... 30 V
4503BQ…
Measuring range logic condition voltage level
1st measuring range
10 … 100 % PIN1 = 0 UPIN1,7 = 0 ... 2 V
2nd measuring range
10 … 90 % PIN1 = 1 UPIN1,7 = 3,5 ... 30 V
For each measuring range the logic condition at PIN 1 must
continue.
Optional the measuring range can be switched via the
RS-232C interface.
7.6.2 Digital output, measuring value via RS-232C
With this option torque values can be sent via the
RS-232C serial interface. Additional notes are in the
chapter "RS-232C communication".

7.6.3 Connection diagram standard sensor
Fig. 6: Connection diagram of 12 pin built-in
connector (standard)
Extraneous EMC interference on the measurement
cable must be avoided (e.g. triggered by switched
inverter of high-performance drive or brake machines)!
In this case, start the control function for drives that are
switched off.
In order to avoid errors, please note if cables are longer
than 10 m and conductors are distributed, that the speed
signal is isolated from the torque signal by feeders, just as
in the connector.
U
B
GND (A) and AGND (D) must not be connected
(electronics can be damaged).
It is recommended to use a differential amplifier input
for the output UA/AGND.

7.6.4 Connection diagram with range selection/RS-232C Interface
Fig. 7: Connection diagram of 7 pin built-in connector
* To ensure electrical isolation within the sensor, it’s
recommended to switch control activation signal via 7 pin
plug (PIN 4 and PIN 7)
** In EMC critical areas it’s reasonable to use a galvanic
decoupled RS-232C interface at the personal computer
(PC) side.

Running the measurement cable
4503B_002-736e-02.22 Page 19
8. Running the measurement cable
Do not run in parallel with high-current or control
cables.
Do not run near strong electromagnetic fields, such as
transformers, welders, contactors, motors, etc. If this
cannot be avoided, run the measurement cable in
a grounded steel shield conduit.
If this cannot be avoided, lay the measuring cable in a
grounded armored conduit.
Avoid excess lengths of cable. If this is not possible, do
not coil the excess length into a closed ring. Keep the
induction area as small as possible.
Fig. 8: Running the measurement cable
Risk of interference with the measurement signal
due to electromagnetic fields
A bifilar run reduces the active induction area.
