PFA type Pressure Transmitter
VSST(SF/RR/WT/WF) series0.4MPa–1MPa
- Suitable for pressure measurement of ultrapure water and corrosive media such as strong acids or alkalis.
- Integrally molded PFA body offers high leak-proof performance.
- Employs a leak indicator to alert you in case gas permeation occurs.
| Measured medium | Ultrapure water, strong acid, strong alkali or other media that will not corrode PFA |
|---|---|
| Pressure Type | Positive, compound and negative pressures can be measured. |
| Measured Range | Rated capacity: 0(-0.1) to 0.4, 0.6, 1MPa Specify more than 60% of rated capacity as the calibration range(F.S.). *(Example) Rated capacity 0.4MPa: 0 to 0.2MPa (=0.2MPaF.S.) → Manufacture is impossible. -0.1 to 0.2MPa (=0.3MPaF.S.) → Manufacture is possible. |
| Output type | Specify among 4 to 20 mA (2 wire system), 1 to 5 V, 0 to 5 V, 0 to 10 V. |
