Details

Service intended

P690 differential pressure gauge series are designed to measure differential pressure from 25 kPa to 2.0 MPa at static pressure up to 10 MPa and have inductive contact. P690 series are designed to control alarm for differential pressure, providing the right time to replace air and sludge filter during the process.

Nominal diameter	160 mm
Accuracy	±1.6 % of full scale
Scale range (MPa, kPa, bar, mbar)	0 ~ 25 kPa to 0 ~ 0.25 MPa 0 ~ 0.4 MPa to 0 ~ 2 MPa
Static pressure	Max. 10 MPa
Working temperature	Ambient : -20 ~ 65 °C -40 ~ 65 °C (With silicone filling) Fluid : Max. 100 °C
Degree of protection	EN60529/IEC529/IP65
Temperature effect	Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately ±0.5 % per 10 ℃ of full scale
