Applications of Pressure balances

Primary standard for defining the pressure scale in ranges of: up to 100 bar / 1,500 psi pneumatic respectively up to 400 bar / 5,000 psi pneumatic (with gas to oil separator) and up to 5,000 bar / 70,000 psi hydraulic

Reference instrument for testing, adjusting and calibrating pressure measuring instruments in factory and calibration laboratories

Self-sustaining complete system also suitable for on-site measurements / calibrations (no need of power supply and external pressure supply)

• Pressure P is applied on a known Area A of a piston and balanced by the Force F generated by a known Mass M

• P= F/A, which is then corrected by “environmental parameters”: Local gravity Distortion coefficient Temperature effect, etc …
