ELECTRICAL CONNECTION

If a suitable amplifier is connected (e.g. QuantumX from HBM), the amplifier electronics
will read the TEDS chip and parameterization will then be implemented automatically,
without any intervention required by the user.
The chip content can be edited and modified with suitable hardware and software. This
can be achieved with HBM’s Quantum Assistant or DAQ CATMAN software, for instance.
Please pay attention to the operating manuals of these products.
8.2 Electrical connection of measuring amplifier with amplifier module
8.2.1 General information
If you have ordered the sensor with an inline amplifier, the inline amplifier and force trans­
ducer form a measurement chain that cannot be separated. The measurement chain is
accordingly calibrated as a unit, meaning the test record (or calibration certificate) di­
rectly indicates the relationship between the force (in Newtons) and the output signal (in
V or mA).
In order to guarantee a reliable measurement even under the influence of
electromagnetic fields, the housings of the inline amplifier and the sensor are connected
to the cable shield. This means that the sensor, cable and amplifier housing form a Fara­
day cage. This concept is failsafe and highly insensitive to interference.
Note that the thread of the M12 device plug, by which you make the connection to the
next link in the measurement chain, is also electrically connected to the amplifier housing,
and so ultimately to the sensor housing.
If the housing of the inline amplifier and the sensor are at different electrical potentials,
compensating currents may flow through the cable shield and influence the measure­
ment. So make sure that all components are at the same electrical potential. If you are
daisy-chaining the shield of the cable connected to the M12 device plug, the next compo­
nent in the chain must also be set to the potential of the sensor and amplifier housing.
Use low-ohm connections for potential equalization.
A compressive force load will result in a rising current or voltage signal.
