Details

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
