Calibration of differential pressure gauges, transmitters and leak testers

Tradelab performs the calibration of differential pressure gauges and transmitters with ENAC (ILAC) accreditation, both in the laboratory and on-site.

Calibration is often carry out by comparison with reference standards.

In high precision instruments (standards), calibration can be performed with deadweight scales to improve calibration uncertainty.

In the laboratory and up to a line pressure of 10 bar, Tradelab can calibrate leak testers whose operating principle is based on the measurement of the differential pressure.

ENAC ILAC calibration

Calibration of differential pressure gauges and transmitters with ENAC (ILAC) accreditation by comparison method, within the range from 1 Pa to 1 MPa (0.01 mbar at 10 bar) and up to a 10 bar pressure line. In a permanent laboratory.
Calibration of differential pressure gauges and transmitters with ENAC (ILAC) accreditation by balance, within the range from 3 kPa to 2 MPa below 3 kPa line pressure and from 1 Pa to 1 MPa for line pressures from 3 kPa to MPa, as long as the total pressure of the assembly (line pressure + maximum range preassure) does not exceed 2 MPa. In the permanent laboratory.
Calibration of differential pressure with next atmospheric line pressure with ENAC (ILAC) accreditation within the range from 1 Pa to 1 MPa (0.01mbar to 10 bar). On-site calibration.
For more information refer to the calibration annex:

Technical Annex

Information required to perform a calibration budget:

Minimum and maximum measurement range.
Line pressure, when it is different from the atmospheric pressure.
Points to calibrate below 20% (10%, 5%, 3% ...) if required.
Calibration site (on-site or in laboratory).
