The model 8510 bending beam load cell is suitable for measuring small and extremely small applied forces. The mechanical overload protection available for all measuring ranges prevents the sensor from being damaged by excessively high static and quasi-static loads which can occur during measurement and installation.
The sensor can be extended axially, e.g. by a finger, which does not influence the measuring.
Essential application of this sensor include measurement and testing of the following components:
Switches (limit-, micro- and toggle-switches)
Buttons
Contact coupling and contact decoupling forces
Frictional forces
Spring characteristics
Tension of wire and string windings
The sensor element consists of a double bending beam with applied strain gauges.
Changes in the ohmic resistance of the strain gauge fullbridge caused by applied forces are converted into electrical voltages. The precise value (characteristic value) of the output voltage, resulting from the application of a rated force to the sensor, is specified in the accompanying calibration protocol.
The sensor has to be mounted by two screws on the cable side. The opposite side is meant to receive applied forces (loads).
Once the rated stress or strain is exceeded by 20 %, further deflection of the bending beam is prevented by an integrated, mechanical stop. This protects the sensor element against permanent deformation.
