E+E accredited laboratory performs calibrations of measuring devices for absolute, relative and differential pressure in the ranges:
|Calibration||Calibration object||Measurement conditions||Measurement range||Calibration uncertainty|
|OEKD||Lab||Absolute pressure sensor||23 °C ±3 °C||0,1 to 1 bar|
1 to 21 bar
21 to 101 bar
0,01% from mv + 0,00018 bar
0,011% from mv + 0,00006 bar
|OEKD||Lab||Relative pressure sensor||23 °C ±3 °C||-0,9 to 0 bar|
0 to <20 bar
20 to 100 bar
0,01% from mv + 0,00028 bar
0,011% from mv + 0,00016 bar
|OEKD||Lab||Differential pressure sensor||23 °C ±3 °C||0 to 0,3 bar|
0,3 to 9 bar
|0,19% from mv + 0,00005 bar|
0,16% from mv + 0,00006 bar
A pressure calibrator is used for the calibration of absolute and relative pressure meters.
The generator consists of a pressure regulating unit, as well as two quartz relative pressure sensors for reference, and a quartz barometer.
The pressure drop of a gas stream is measured at a needle valve for the calibration of differential pressures.
