产品描述

Service intended

Sturdy industrial pressure gauge designed in compliance with the operational safety requirements of EN 837-1. Reliable pressure gauge for the machine and plant. For gaseous and liquid media that are not highly viscous or crystallising and will not attact copper alloy parts.

Nominal diameter	63, 100 and 160 mm
Accuracy	P2532 (63 mm) : ±1.6 % of full scale P2534 (100 mm) and P2536 (160 mm) : ±1.0 % of full scale
Scale range (MPa, kPa, bar)	63 mm : -0.1 ~ 0 to 0 ~ 35 MPa 100 and 160 mm : -0.1 ~ 0 to 0 ~ 100 MPa
Working pressure	Steady : 75 % of full scale (63 mm) 100 % of full scale (100 and 160 mm) Over range protection : 130 % of full scale
Working temperature	Ambient : -20 ~ 60 ℃ Fluid : Max. 60 ℃
Degree of protection	EN60529/IEC529/IP65
Temperature effect	Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately ±0.4 % per 10 ℃ of full scale
