Differential pressure gauge with bellows element

Type: P670

 

Service intended

 

P670 differential pressure gauge series are designed to measure differential pressure from 4 kPa to 2.0 MPa at static pressure of 4 and 10 MPa. A set of two stainless steel bellows 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)

 

0 ~ 4 kPa, 6 kPa, 10 kPa (P671 model)
0 ~ 25 kPa to 0 ~ 0.25 MPa (P672 model)
0 ~ 0.4 MPa to 0 ~ 2.0 MPa (P673 model)

 

Static pressure

 

P671 : Max. 4 MPa
P672 and P673 : Max. 10 MPa

 

Working temperature

 

Ambient : -20 ~ 65 °C
Fluid : Max. 100 °C

 

Degree of protection

 

EN60529/IEC529/IP67

 

Temperature effect

 

Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
±0.5 % per 10 ℃ of full scale
