¡ß Differential pressure gauge with bellows element ¡ß
¡Ü Model : P671-P672-P673
¡Ü 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.
¡Ü Nominal diameter : 160mm
¡Ü Accuracy :
- ¡¾ 1.0% of full scale
- ¡¾ 1.6% of full scale
¡Ü Scale range (MPa, kPa, bar) :
- P671 model : 0 ~ 4 kPa, 6 kPa, 10 kPa
- P672 model : 0 ~ 25 kPa to 0 ~ 0.2 MPa
- P673 model : 0 ~ 0.25 MPa to 0 ~ 2.0 MPa
¡Ü Static pressure :
- P671 : Max. 4 MPa
- P672 and P673 : Max. 10 MPa
¡Ü Working temperature :
