The bending plate inside this Burster load cell is equipped with strain gauges which, on the exertion of a force, supply a bridge- output voltage directly proportional to the measurement variable. The center axis of the tension/compression load cells incorporates a continuous thread through which the measurement force is applied free from lateral or torsion force either using a load application button or an application-specific adapter part. Starting at a measurement range of 0 to 5 kN, the measurement accuracy is ideal if the load cell has been mounted on a level, hard and polished base. This condition is not necessary for small measurement ranges of 0 to 2 kN due to 3 special knife-edge bearings (see dimensional drawing 1).
Structural measures should be taken to avoid exposing the load cell to lateral forces (for instance, mounting on movable bearings, levers held by roller bearings). Attachment via the clearance bore holes integrated in the external ring allows simple handling of the sensor.
A stop serves as overload protection against damages caused by impermissible high compression forces (option up to measurement range 0 to 20 kN). Lateral forces of up to 5% nominal strength only have little influence.
