Service intended

P660 gauge series are differential pressure gauge is designed to measure differential pressure from 4 kPa to 2.5 MPa at static pressure of 10, 25 MPa. A set of two stainless steel diaphragm 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, mbar)	0 ~ 4 kPa to 0 ~ 40 kPa Flange size / DN 140, Max. static / 10 and 25 MPa 0 ~ 60 kPa to 0 ~ 2.5 MPa Flange size / DN80, Max. static / 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
