Specialized manufacturer of Digital Pressure Meters and Load Cells

VALCOM CO.,LTD.

 

General-purpose Pressure Transducer for Middle High Pressure
VPRQ(IS)/VPRQF(IS) series (For explosion-proof)
1MPa–100MPa

  • Sensor machined integral with diaphragm offers durability and long life.
  • Economy type that offers quick delivery and low price.
  • Pressure port diameter is as large as 9.5 mm, which allows less sludge or fluid to accumulate
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.
Rated capacity 1–100MPa
