Measured variable pressure
All pressure measuring devices for negative and positive overpressure and absolute pressure are calibrated, including pressure transmitters, transmitters and pressure measuring cells. The calibration is only carried out as a works calibration.

The calibration takes place at 20%, 40%, 60%, 80%, 100% of the measuring range (as well as 0 bar r) in ascending and descending direction at (23 ± 1) ° C. The average of these two series of measurements is given in the calibration certificate.
If desired, the calibration can also be carried out at other temperatures in the range from -20 ° C to 80 ° C. For this purpose, the pressure measuring device is brought to the target temperature in a temperature cabinet.
