        Service intended

        P670 differential pressure gauge series are designed to measure differential pressure from 4 kPa to 2.0 MPa at static pressure of 4 and 10 MPa. A set of two stainless steel bellows mounted on a force balance allows direct reading of the actual differential pressure.

        Nominal diameter 100 and 160 mm
        Accuracy ±1.0 % of full scale
        ±1.6 % of full scale
        Scale range (MPa, kPa, bar) 0 ~ 4 kPa, 6 kPa, 10 kPa (P671 model)
        0 ~ 25 kPa to 0 ~ 0.25 MPa (P672 model)
        0 ~ 0.4 MPa to 0 ~ 2.0 MPa (P673 model)
        Static pressure P671 : Max. 4 MPa
        P672 and P673 : Max. 10 MPa
        Working temperature Ambient : -20 ~ 65 °C
        Fluid : Max. 100 °C
        Degree of protection EN60529/IEC529/IP67
        Temperature effect Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
        ±0.5 % per 10 ℃ of full scale
