P701 Series_Compact design diaphragm seal pressure gauge
Service intended
P701 series are designed for diaphragm seal to be combined with a pressure gauge. It is suitable for corrosive, contaminated, hot or viscous pressure media in chemical and food process.
| Design | Internal diaphragm, upper and under flange welded no sealing and compact design |
| Accuracy | P2522 (63 mm) and P2523 (80 mm) : ±1.6% of full scale P2524 (100 mm) : ±1.0% of full scale |
| Scale range (MPa, kPa, bar) | -0.1 ~ 0 to -0.1 ~ 2.4 MPa 0 ~ 0.1 to 0 ~ 7 MPa |
| Filling liquid | Silicone oil |
| Working pressure | Steady : 75 % of full scale (63 and 80 mm) 100 % of full scale (100 mm) Over range protection : 130 % of full scale |
| Working temperature | Ambient : -20 ~ 65 °C Fluid : Max. 100 °C |
| Degree of protection | EN60529/IEC529/IP65 |
| Temperature effect | Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately ±0.5 % per 10 ℃ of full scale |
