Deadweight pressure gauge MP-400
Also, this device can be called: MP400, MP 400.
Deadweight gauges MP-400 - are widely used for benchmark results in the field of heat engineering. With their help, you can easily find a high pressure liquid or gas.
At the heart of robots instrument MP-400 is the principle of "non-compacted piston" - the total weight of the piston weighbridge, and installed on the balances of goods measured by the pressure acting on the lower end of the piston.
Scope MP-400: standard for verification and calibration of measuring the excess pressure transducers, model and technical gauges and other measuring tools, as well as the deadweight tester lower accuracy class in the laboratory.
Accuracy class MP-400 - 0.01, 0.02, 0.05 (Table 1).
Upper limit of measurement (play) - 40 MPa (400 kgf/cm 2).
The lower limit of measurement (playback) - 0.1 MPa (1 kgf/cm 2).
