3.3.2 Maintenance
In its capacity as a sensor, BROSA force measuring pins are maintenance-free. As load-
transmitting elements, however, they are subject to mechanical stress, requiring regular
inspections of the fault-free state of each force measuring pin. The intervals between
inspections depend on the intensity of use and must be determined by the end-user. Additional
lubrication holes are not necessary for the sensor to function, but are used to lubricate
secondary components, so the end-user is responsible for the lubrication cycles.
An inspection includes the following points:
- Visual inspection for damage to the measuring body and wiring as well as
contamination.
- Function test/plausibility check
The causes of existing errors are to be identified and remedied. If the test indicates an improper
sensor state, it must be taken out of operation. If a malfunction or damage is detected on the
sensor, it must be sent to the manufacturer's factory for diagnosis and, if necessary, repaired.
WARNING! The sensor may only be repaired at the factory. Intervention (e.g., opening,
mechanical processing and the like) done by parties other than the manufacturer means the
safe operation of the sensor is no longer ensured and voids the guarantee and warranty.
3.4 Disassembly
We recommend performing the following actions in the order given.
a) Establishment of a load-free state at the measuring point: The force measuring pin is
to be unloaded before removal.
WARNING! Removal of a force measuring pin under load poses serious dangers to the
life and limb of bystanders and can cause major damage. This is therefore not permitted.
b) Undoing the electrical connection
c) Remove the mechanical securing elements
d) Remove the force measuring pin
WARNING! If the force measuring pin is to be reused, it must not be removed using
impact tools!
