Specialized manufacturer of Digital Pressure Meters and Load Cells



Low Pressure Transmitter (Wetted Part: SUS316L)
VPNPR(G) series
100kPa–1700kPa abs

  • Diaphragm structure enables high accuracy measurement even in lower pressure range. (Non Linearity: ±0.25%R.C.)
  • Highly leak-proof and can be used even at high vacuum.
  • 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: 50 kPa to 1700 kPa).
