Loadcell Calibration and Repair

Loadcell Calibration Rigs

We have a number of loadcell calibration rigs that all use equipment whose calibration is traceable to European standards. Traceability is maintained by the use of external calibration laboratories and a programme of equipment calibration comparisons carried out in-house.

Deadweight Calibration Rigs

These apply forces to the loadcell being calibrated using accurate weights. The output of the loadcell is measured using a precision DC ratio meter calibrated by the National Physical Laboratory. We have three rigs for forces from 0.1N to 10kN (10gf to 1 tonnef). We have weights available from 1g to 20kg with a total weight in excess of 1 tonne. 1gf equates to a force of approximately 0.01N.

Transfer Calibration Rigs

Transfer calibration rigs apply forces using hydraulic rams. The force is measured using an accurate reference loadcell. The outputs of both loadcells are measured using precision DC ratio meters. The reference loadcells and DC ratiometers are calibrated by the National Physical Laboratory.

Rig A

Maximum force of 80kN (8 tonnef) in compression.

Rig B

Maximum force of 800kN (80 tonnef) in compression and tension.

Rig C

Maximum force of 1000kN (100 tonnef) in compression and tension.
Maximum force of 2000kN (200 tonnef) in compression only.

Rig D

Maximum force of 100kN (10 tonnef) in compression and tension.
