Force and torque


Calibration of force

VTT MIKES-Kajaani performs force calibrations from 1 N to 1.1 MN. Calibrated measurement devices are usually force transducers, force measurement devices, balances (eg. hook, wheel weight and airplane) and pull force testers. The smallest measurement uncertainty is 2×10-5.

The calibration of force is based on the ISO 376 standard. The force calibration from 1 N to 110 kN is carried out in dead weight force standard machines. A dead weight machine is a mechanical structure that generates force by subjecting dead weights to the local gravitational field. Hydraulic force standard can be used in the calibrations from 20 kN to 1.1 MN.

Calibration of torque

VTT MIKES Kajaani performs calibrations of torque in the range 0.1 Nm ... 20 Torque.jpgkNm, the smallest uncertainty being 5×10–4. The calibration of torque is carried out using reference standards for torque or standards based on reference sensors.
