产品描述

Service intended

P757 series have diaphragm seal to be combined with a pressure gauge. These series are suitable to be used for the situation where corrosive, contaminated, hot, and viscous pressure mediums are present such as a chemical and food process.

Nominal diameter	63, 80 and 100 mm
Accuracy	63 and 80 mm : ±1.6 % of full scale 100 mm : ±1.0 % of full scale
Scale range (MPa, kPa, bar)	Refer to pressure unit and range table Depending on diaphragm size and process conditions
Working pressure	Steady : 75 % of full scale Over range protection : 130 % of full scale
Working temperature	Ambient : -20 ~ 65 °C Fluid : Max. 100 °C
Temperature effect	Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately ±0.5 % per 10 ℃ of full scale

Standard features

Body	Stainless steel (316SS)
Process connection	Stainless steel (316SS) Screw connection
Diaphragm	Stainless steel (316L SS)
Certificates	ATEX Ex II GD c IIC TX
