Valcom VNF Series
- Suitable for measurement of viscous media since the flush type (no feed port) wetted part is hardly clogged up.
- Pressure port has SUS316L stainless steel wetted surfaces, enabling measurement of wide range of media.
- Diaphragm structure enables high accuracy measurement even in lower pressure range.(Non Linearity: ±0.25%R.C.)
- Atmospheric pressure reference and absolute pressure reference available.
| Measured medium | Water, oil, gases or other media that will not corrode SUS316L. |
|---|---|
| Pressure type | Positive, compound, negative and absolute pressures can be measured. |
| Measured Range | Can be specified within the range of 100 kPa to 1700 kPa of rated capacity (Calibration range: 50 kPa to 1700 kPa).Specify more than 50% of rated capacity as the calibration range. |
| Output type | Specify among 4 to 20 mA (2 wire system, 4 wire system), 1 to 5 V, 0 to 5 V, and 0 to 10 V. |
