Laboratori i Presionit

The key activities of the pressure laboratory are the provision of measurement traceability at international level for the physical unit of pressure and dissemination of the force unit to the lowest level up to the end user.  International level measurement traceability is achieved through calibration of pressure balances in a National Institute of Metrology, which has declared its Calibration and Measurement Capabilities to BIPM KCDB for this calibration, in the ranges from 0 – 700 bar.
To provide calibration services for DPM clients, the laboratory of pressure uses:

Digital piston-cylinder system with two measuring ranges:

   •    0 – 2 bar, gas , uncertainty U = 0.5 Pa + 4.0 x 10-5 P
•    0 – 1000 psi (0 – 70 bar), oil – gas, uncertainty U = 28 Pa + 4.7 x 10-5 P

 

 

 

 

Pressure balance with measuring ranges:

•    0.2 – 10 bar; accuracy 0.008 %
•    0.4 – 100 bar; accuracy 0.008 %
–    Hydraulic pressure balance (with piston-cylinder system with measurement field 0 -120 bar; measurement accuracy 0.025 %;
–    Hydraulic pressure balance (with dual piston-cylinder systems water operated) with measurement field  0-350 bar; measurement accuracy 0.025 %;
–    Hydraulic pressure balance (with dual piston-cylinder systems) with measurement field 0 – 700 bar; measurement accuracy 0.025 %;
–    Digital pneumatic manometer with measurement field 0–40 bar; U = 0.05 bar
–    Digital barometer; U = 0.05 mbar
