Typical Applications for the Series 937B Controller
•
Wide pressure measurement range including high vacuum and ultra-high (UHV) vacuum
pressures.
•
Pressure measurements with multiple sensing methods (ionization, thermal conductivity,
capacitance manometer).
•
Where a single analog output is needed over a wide range from multiple sensors.
•
Pumpdown and process sequencing using relay set points.
•
Pressure control in vacuum systems using relay set points.
•
Sensing abnormal pressure situations and initiating appropriate security measures using the
relay set points.
•
Controlling system pressure by using the analog output as the input to an automatic pressure
controller.
•
Starting, stopping, or sequencing system processes using relay set points.
•
Measuring backfill pressures.
•
Leak testing vacuum systems.
•
Controlling accelerator and light source vacuum systems.
•
Maintaining smooth control of a wide range of pressures through the use of the combined
analog outputs of up to 3 sensors.
•
Using averaged analog output from up to 3 Capacitance Manometers with the same range for
critical process control.
•
Fast relay control by a Cold Cathode sensor for high vacuum protection.
