Capacitance Diaphragm Gauge M-342DG

Capacitance Diaphragm Gauge M-342DG

The capacitance gauge M-342DG is a diaphragm gauge that enables accurate, stable pressure measurement with minimum zero adjustment.

This is achieved using a small silicon MEMS chip as the pressure sensor unit to minimize the influence from the outside environment such as changes in temperature, vibrations, and atmospheric pressure.

Capacitance Diaphragm Gauge M-342DG CE_marking RoHS


  • High precision, stable pressure measurement
    ・Excellent zero point stability.
    ・Has low temperature dependence providing excellent stability without the need of a temperature
       adjustment mechanism.
    ・Excellent anti-vibration noise performance.
  • Compact and low power consumption
    ・200g, W46mm × H49mm × L70mm compact, lightweight.*1
    ・Power consumption 0.5W.

    *1:Size and weight of the coupling NW16 specifications


    Supports a wide range of general industy applications such as medical and food in addition to semiconductor manufacturing equipment, panel display munufacturing equipment, and other vacuum equipment.*2

      *2:Not suitable for applications where corrosive gas is used.
