        詳細介紹


        Service intended

        P256 series are made with a solid plate wall and a blow-out back. Its stainless steel case and cover have a good appearance. It has the excellent proof against corrosion and chemical attack. Suitable for protection against damage to the measuring element when high overpressure is applied to the gauge instantaneously. Max overpressure is up to 4 times of measuring range.

         

         

        Nominal diameter 100 and 160 mm
        Accuracy ±1.0 % of measuring range
        Scale range (MPa, kPa, bar) -0.1 ~ 0 to 0 ~ 4 MPa
        Working pressure Steady : 100 % of full scale
        Over range protection : 4 times the measuring range
        Working temperature Ambient : -40 ~ 65 ℃
                       -20 ~ 65 ℃ (With glycerin filling)
                       -40 ~ 65 ℃ (With silicone filling)
