Calibration of Pressure Transducers at The National Laboratory

Purpose

The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and  spreading metrological competens and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden. 

A calibration performed at a national laboratory fullfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 

Method

The calibration object is connected to the National Laboratory's reference standards and the calibration is carried out in pressure points evenly distributed over the pressure range. The upper range for calibrations is 50 MPa.

Since the National Laboratory is the highest calibration body in Sweden, calibrations are performed here with the highest possible traceability.

The pressure media used at the National Laboratory are nitrogen gas, air, oil and water.

Deliveries

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.
