Ceramic Capacitance Manometer

CCMT-D Series

CCMT-10D

アルバック

The CCMT-D series is a capacitance manometer, which detects static electric capacitance occurring when a barrier membrane made of ceramic (alumina) is deformed by changes in gas pressure.

Features

  • Corrosion resistant ceramic sensor
  • Exellent long term signal stability
  • Whole pressure measurement that does not depend on the gas types is possible
  • Shorten the warm-up Time
  • Temperature compensation
  • Sensor protected against contamination
  • Push button zero point adjustment
  • Accurate linear output (DC 0 to 10V)
  • Wide range voltage power supply (DC14 to 30V)

Applications

  • Vacuum melting or vacuum heat treatment
  • Thin films deposition system
  • Pressure reduction furnaces
  • Gas exchange or gas sealing etc.
  • PV, FPD manufacturing equipment
