Differential pressure gauge_P620, P630 series

High-quality products, preferential prices, perfect after-sales service




Detailed Introduction

Service intended

P620 and P630 series are designed to measure differential pressure from 1 kPa to 1.5 MPa at static pressure up to 5 and 25 MPa. A set of 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 ~ 1 kPa to 0 ~ 50 kPa
0 ~ 0.1 MPa to 0 ~ 1.5 MPa
Static pressure P620 : 5 MPa
P630 : 25 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
