Equipment context
- Applied Materials Centura/P5000 vacuum systems
Applications
vacuum monitoringflow detectioncassette or wafer presence detectioninterlock systemsrough-vacuum pressure measurementloadlock or chamber vacuum monitoringP5000/Centura vacuum gauge replacement
How it works
A sensor, switch, gauge, or detector used to monitor pressure, flow, position, light, or system state.
Set point, range, wiring, output type, and process compatibility must match the tool and safety logic.
