        Service intended

        The P650 series are designed to measure a differential pressure from 25 kPa to 2.0 MPa at static pressure up to 10 MPa, and have electrical contact. A set of two stainless steel bellows mounted on a force balance allows direct reading of the actual differential pressure. These models are designed to control and alarm for a differential pressure.

        Nominal diameter 160 mm
        Accuracy ±1.0 % of full scale
        ±1.6 % of full scale
        Scale range (MPa, kPa, bar, mbar) 0 ~ 25 kPa to 0 ~ 0.25 MPa (P651 model)
        0 ~ 0.4 MPa to 0 ~ 2.0 MPa (P652 model)
        Static pressure Max. 10 MPa
        Working temperature Ambient : -20 ~ 65 °C
        Fluid : Max. 100 °C
        Degree of protection EN60529/IEC529/IP65
        Temperature effect Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
        ±0.5 % per 10 ℃ of full scale
