3 Non-rotating torque sensors, model
8625/8630/8631, USB version
3.1 Electrical connection
NOTICE
The USB socket is supplied with a protective dust cap fitted. Before putting the sensor
into use, this cap must be levered off, without damaging it. It is not meant to be cut off!
1. Take the cap off the USB socket.
2. Connect the torque sensor to a computer using the supplied USB cable.
3. Please be sure to follow the instructions in section 3.2 Power supply on page 7.
3.2 Power supply
The device draws 200 mA from the USB port. Usually this is not a problem for desktop PCs.
For laptops, however, several USB ports may share one power supply that is additionally loaded by other
connected USB devices (mouse etc.) Therefore, under some circumstances, the torque sensor may be
supplied with too little power and cannot register its presence. In this case, you need to connect the
torque sensor to the laptop via an active USB hub.

3.3 Connector pin-out
The USB interface complies with the USB 2.0 standard and the pin assignment is as usual. The built-in
connector on the torque sensor is for a “Micro USB” plug.

3.5 Running cables
In general the following applies:
•The torque sensor must be grounded via its mounting screws.
•The USB cable length should not exceed 2 m. For longer cables it may be necessary to
connect an active USB hub in the cable link to avoid losing the USB connection.

4 Rotating torque sensors, model 8655/8656/8661,
USB version
4.1 Electrical connection
The USB socket is supplied with a protective dust cap fitted. Before putting the sensor into use, this cap
must be levered off with a suitable tool, without damaging it. It is not meant to be cut off!
1. Carefully prise off the protective cap using a pointed tool.
2. Take the cap off the USB socket.
3. Connect the torque sensor to a computer using the supplied USB cable.
4. Please be sure to follow the instructions in section 3.2 Power supply on page 7.
5. The torque sensor goes through a self-test mode lasting 4 seconds after power-up.
Once the self-test has finished, all the LEDs – if fitted – light up solidly for about 1 s.
Then the sensor is ready for operation.

4.2 Power supply
After the torque sensor is connected to the USB port, the sensor identifies itself as a “high power device”.
In this case, the device draws 495 mA from the USB port. Usually this is not a problem for desktop PCs.
For laptops, however, several USB ports may share one power supply that is additionally loaded by other
connected USB devices (mouse etc.) Therefore, under some circumstances, the torque sensor may be
supplied with too little power and cannot register its presence. In this case, you need to connect the
torque sensor to the laptop via an active USB hub.
Note: The actual power consumption is: P = 5 V * 0.35 A = 1.75 VA.
4.3 Connector pin-out
The USB interface complies with the USB 2.0 standard and the pin assignment is as usual. The built-in
connector on the torque sensor is a “USB Mini B” plug.

5.3 Setup
5.3.1 Setting up rotating sensors
On the “Settings” tab, you can specify the units and conversion factors to be used for the relevant
measurement channels. Units suitable for the measured variable should be selected, otherwise errors
may occur when displaying the measured value and in its interpretation.
With “Number of Averages” you can set the number of individual measured values to be used to form an
arithmetic mean. The value can be set in the range N = 1 to N = 20. When N = 1, averaging is not
performed. In this case, the value at the output is refreshed every 10 µs. This corresponds to 100 000
digitizations per second. So if you select N = 20, for example, then a measuring time of 200 µs is needed
for a new value at the output (20 x 10 = 200 µs). The averaging has a direct effect on the measured
values per second. The higher the averaging value, the fewer measured values per second are possible.
If the torque sensor includes the speed/angle measurement option, you can switch between these two
measurement modes on this tab.
If the torque sensor is the optional dual-range version, you can also select the required measurement
range here. Applying the settings saves them in the sensor.

5.3.2 Setting up non-rotating sensors
On the “Settings” tab, you can specify the units and conversion factors to be used for the relevant
measurement channels. It is important to select units that make sense and are suitable for the measured
variables, otherwise errors may occur when displaying the measured value.
With “Number of Averages” you can set the number of individual measured values to be used to form an
arithmetic mean. The value can be set in the range N = 1 to N = 50 000. When N = 1, averaging is not
performed. In this case, the voltage value at the output is refreshed every 10 µs. This corresponds to
100 000 digitizations per second. So if you select N = 50 000, for example, then a measuring time of
5 seconds is needed for a new voltage value at the output (50 000 x 10 = 0,5 s). The averaging has a
direct effect on the measured values per second. The higher the averaging value, the fewer measured
values per second are possible.
Disable the low-pass filter if you set a value N ≠ 1.
Filter settings: Set the averaging value to N = 1 if you select a cut-off frequency ≠ OFF.
The low-pass filter is a digital filter designed as a first-order low-pass filter.
Apart from the “OFF” setting, you can select various cut-off frequencies. The cut-off frequency is the
frequency at which the output signal is attenuated by -3 dB, corresponding to about 70.7 % of the signal
at very low frequencies.
If the torque sensor is the optional dual-range version, you can also select the required measurement
range here, or activate switching by a voltage level.
Applying the settings saves them in the sensor.
