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 newly developed 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.
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.
・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
Applications
*2:Not suitable for applications where corrosive gas is used.
