Sensor calibration is a sound investment in the future. Calibration is indispensable to ensuring consistent quality of your measurement results. Moreover, calibrating your sensors is an integral part of ISO 9001 certification.
There are different types of calibrations available. In most cases you can opt for a basic working standard calibration or calibration against a higher-level standard such as calibration in line with ISO 376 and DAkkS-DKD-R 3-3 for force transducers or calibration per DIN 51309 or VDI/VDE 2646 for torque transducers. A similar hierarchy of calibration standards is available for other sensor types.
Which type of calibration to choose mainly depends on your requirements and needs.
