Differential deadweight testers «MP-D-100»

This instrument is manufactured with accuracy class from 0.005 to 0.05

Verification and calibration of differential pressure instruments: pressure differential transducers, differential manometers used for utilities revenue metering and other differential pressure instruments of accuracy class 0.01 and lower.

Gauge pressure measuring instruments calibration and verification: pressure calibrators, instrument pressure transducers (sensors), standards and manometers, deadweight testers, with accuracy class of 0.008 and lower within the range from 0.02 to 10 MPa.

Advantages
Actual measurement environment simulation for pressure differential transducers installed at restriction orifice (diaphragm).

Design option for gauge-pressure precise instruments calibration and verification with pressure from 0.02 to 10 MPa.

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

Weights are made of nonmagnetic stainless steel.

Differential deadweight testers MP-D may be optionally equipped with phase separators of different types, high-pressure hoses, and other accessories
