Pressure Transmitter for Flush type Middle High Pressure
VPRF series1MPa–50MPa
- Suitable for measurement of viscous media since the flush type (no feed port) wetted part is hardly clogged up.
- Wetted part constructed integral with diaphragm does not use any sealed liquid, offering durability, reliability and long life.
- Abundant analog output available.
[4–20mA (2 wire system, 4 wire system), 1–5V, 0–5V, 0–10V]
| Measured medium | Water, oil, gases or other media that will not corrode 15-5PH (precipitation-hardened stainless steel). |
|---|---|
| Pressure Type | Positive and compound pressures can be measured. |
| Measured Range | Can be specified within the range of 1 MPa to 50 MPa of rated capacity (Calibration: 0.5 MPa to 50 MPa). |
