3.3 Operation and maintenance
3.3.1 Operation
BROSA force measuring pins operate automatically; attaching tools is not required for
operation. Direct manual intervention by the operator is not necessary; there are therefore no
requirements for the operator to wear protective equipment during operation. However, the
relevant requirements for the device in which the force measuring pin is implemented must
be observed.
BROSA force measuring pins emit neither airborne acoustic noise nor non-ionizing radiation.
Operation of BROSA force measuring pins is permitted only within the parameters and
properties given in the technical datasheets and on the nameplate. These are, among others:
- Measuring range
- Temperature range
- Permissible supply voltage
- Electrical protection class
- Material
It must be ensured that no parasitic influences such as forces transverse to the measuring
direction are transmitted via the force measuring pin.
Inductive or capacitive coupling with the connection cable(s) of the sensor can distort the
measurement result and must be avoided. Some examples of these kinds of couplings can
be caused e.g., by unfavourable cable routing (parallel power lines, frequency converters,
transformers, motors, incorrect grounding/shielding and the like).
When performing electric welding in the vicinity of the sensor, all connections must be
disconnected and isolated. It must be ensured that no welding current is flowing through the
sensor.
WARNING! Operation outside the specified parameters or contrary to existing
properties or improper use can damage the sensor and cause it to fail or lead to faulty
measuring results. If the sensor is overloaded, this can lead to the whole machine being
equally overloaded and possibly endangering its stability.
