Differential pressure gauge with diaphragm element

Type: P660

 

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
