P257 Series

Service intended

P257 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.

Nominal diameter 63, 100 and 160 mm
Accuracy P2572 (63 mm) : ±1.6 % of full scale
P2574 (100 mm) and P2576 (160 mm) : ±0.5 % of full scale
±1.0 % of full scale
Scale range (MPa, kPa, bar) 63 mm : -0.1 ~ 0 to 0 ~ 100 MPa
100 and 160 mm : -0.1 ~ 0 to 0 ~ 200 MPa
Working pressure Steady : 75 % of full scale (63 mm)
             100 % of full scale (100 and 160 mm)
Over range protection : 130 % of full scale
Working temperature Ambient : -40 ~ 65 ℃
               -20 ~ 65 ℃ (With glycerin filling)
               -40 ~ 65 ℃ (With silicone filling)
Fluid : Max. 200 ℃
          Max. 100 °C (With glycerin filling)
          Max. 100 ℃ (With silicone filling)
Degree of protection EN60529/IEC529/IP67
Temperature effect Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
±0.4 % per 10 ℃ of full scale
