Pressure TransmitterPFA type Pressure Transmitter

VSST(SF/RR/WT/WF) series

0.1MPa~1MPa
VSST(SF/RR/WT/WF)
 *Available digital panel meters
   >>Click here for the list.

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)~0.4, 0.6, 1MPa
Specify more than 60% of rated capacity as the calibration range(F.S.).
*(Example)
  Rated capacity : In the case of 0.4MPa
  0~0.2MPa (=0.2MPaF.S.)
       → Manufacture is impossible.
  -0.1~0.2MPa (=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.
