Controllers for Baratron® Vacuum Gauges • Controllers for Mass Flo® Meters
946 Vacuum System Controller Digital Power/Readout
- Simultaneous control and readout for up to six vacuum gauges and/or six mass flow controllers
- Pressure readings from 10,000 Torr down to 10-11 Torr, eliminating the need for individual electronics for each sensor
- Closed-loop pressure control option for use with MKS valves eliminates the need for separate pressure control electronics
- RS232/485 computer control standard in all configurations for ease of system integration
- Flow ratio control using multiple mass flow controllers
- Intelligent communication between gauges enables a reference sensor to span or zero another gauge allowing accurate, continuous measurement over wide pressure ranges
- 12 set point relays included in the base unit for system control flexibility
