    Deadweight pressure gauge MP-250  
    Also, this device can be called: MP250, MP 250.

    Deadweight gauges MP-250 - 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-250 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-250: 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-250 - 0.01, 0.02, 0.05 (Table 1).
    Upper limit of measurement (play) - 25 MPa (250 kgf/cm 2).
    The lower limit of measurement (playback) - 0.1 M and M (1 kgf/cm 2).
    The piston stroke length - at least 10 mm.
    Nominal area of the piston - 0.1 cm 2.
    Maximum deviation from the nominal value of the reduced area of the piston - 1%.
    Nominal value of the mass of the piston with a load device - no more than 0,4 x0, 98 kg.
    Working fluid - transformer oil.
    Working fluid volume - no more than 250 cm 3.
    Dimensions - 400h500h300 mm.
    Weight without cargo - not more than 25 kg.
