Pressure balance   «MP»

The device is available in nine versions: 6, 60, 100, 250, 400, 600, 1000, 1600, 2500 with accuracy class from 0,005 to 0,05

The device is designed for calibrating gauge pressure measuring instruments: pressure calibrators, pressure transducers (sensors), reference and other manometers, pressure balances of accuracy class 0,008 and lower in range from 0,04 to 250 MPa.

Advantages
Piston-cylinder assembly (PCA) made of tungsten carbide provides for significantly reduced (fourfold) temperature effect on measurement results, long-term stability, wear resistance and durability of the device.

Set of weights made of stainless steel (stainless non-magnetic steel for instruments of accuracy class 0,01 and 0,005).

Working fluid for all models — transformer fluid. Hydraulic system for pressure generating includes pre-filling pump and screw press.

Piston-cylinder assemblies (PCA) for MP 60 and MP 600 can be manufactured suitable for using with one and the same set of weights.

Pressure balance can be equipped with RGB or RPG
