Specialized manufacturer of Digital Pressure Meters and Load Cells

VALCOM CO.,LTD.

 

Pressure Transmitter for Flush type Low Pressure (Wetted Part: SUS316L)
VNF series
100kPa–1700kPa
100kPa abs–1700kPa abs

  • 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.)
  • Gauge 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.
