Differential pressure gauge
Model: P620, P630 series
Spec. sheet no. PD06-01
Service intended
P620 and P630 series are designed to measure differential
pressure from 1 kPa to 1.5 MPa at Max. working pressure
up to 5 and 25 MPa. A set of 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 ~ 1 kPa to 0 ~ 50 kPa
0 ~ 0.1 MPa to 0 ~ 1.5 MPa
Max. Working pressure (Static pressure)
P620 : 5 MPa
P630 : 25 MPa
Working temperature
Ambient : -20 ~ 65 °C (With Glycerin filling)
-40 ~ 65 °C (With Silicone filling)
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
