产品描述

Service intended

P680 series are differential pressure gauge is designed to measure differential pressure from 25 kPa to 2.0 MPa at static pressure 10 MPa. A set of two stainless steel bellows mounted on a force balance allows direct reading of the actual differential pressure. The contacts uses a reed switch for warning and control applications.

Nominal diameter	150 mm
Accuracy	±1.0 % of full scale ±1.5 % of full scale
Scale range (MPa, kPa, bar, mbar)	0 ~ 25 kPa to 0 ~ 0.25 MPa (P681 model) 0 ~ 0.4 MPa to 0 ~ 2.0 MPa (P682 model)
Static pressure	Max. 10 MPa
Working temperature	Ambient : -20 ~ 65 °C 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
