Specialized manufacturer of Digital Pressure Meters and Load Cells



Pressure Transmitter for Flush type Middle High Pressure
VPRF series

  • 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).
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.
