CERAMIC CAPACITANCE MANOMETER CCMT-D SERIES
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
