Capacitance Diaphragm Gauge M-342DG

CE RoHS

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.

Components

Features

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