P620, P630 Series_Differential pressure gauge
Service intended
P620 and P630 series are designed to measure differential pressure from 1 kPa to 1.5 MPa at static 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 |
| Static pressure | P620 : 5 MPa P630 : 25 MPa |
