Specialized manufacturer of Digital Pressure Meters and Load Cells

VALCOM CO.,LTD.

 

G1/4 Flush type Pressure Transmitter
VFM series
1MPa–20MPa

  • Small design (G1/4 thread)
  • 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.
Measured medium Water, oil, gases or other media that will not corrode SUS630.
Pressure Type Positive pressure can be measured.
Measured Range Rated capacity: 1 to 20MPa
Output type 4 to 20mA (2 wire system)
