Specialized manufacturer of Digital Pressure Meters and Load Cells

VALCOM CO.,LTD.

 

PFA type Pressure Transmitter
VSST(SF/RR/WT/WF) series
0.4MPa–1MPa

  • Suitable for pressure measurement of ultrapure water and corrosive media such as strong acids or alkalis.
  • Integrally molded PFA body offers high leak-proof performance.
  • Employs a leak indicator to alert you in case gas permeation occurs.
Measured medium Ultrapure water, strong acid, strong alkali or other media that will not corrode PFA
Pressure Type Positive, compound and negative pressures can be measured.
Measured Range Rated capacity: 0(-0.1) to 0.4, 0.6, 1MPa
Specify more than 60% of rated capacity as the calibration range(F.S.).
*(Example)
Rated capacity 0.4MPa:
0 to 0.2MPa (=0.2MPaF.S.) → Manufacture is impossible.
-0.1 to 0.2MPa (=0.3MPaF.S.) → Manufacture is possible.
Output type Specify among 4 to 20 mA (2 wire system), 1 to 5 V, 0 to 5 V, 0 to 10 V.
