Temperature Indicator

Installation and Operation Instructions

The Cryo-Torr Vacuum-Pump Temperature Indicator, Part No. 8042001G003, or

G004 shown in Figure 1, is used with Cryo-Torr high-vacuum pumps, to monitor

cryopump operating temperatures. With User-supplied switch gear, the indicator

can be used in multiple installations. In cryopumps provided with a silicon diode

sensor, the indicator is easily connected to the cryopump with an electrical

cable. The panel readout is in Kelvin, and has a range from 10K to 320K. The

indicator has two set points that are adjustable over this range. When the vacuum

pump temperature reaches either setpoint, electrical contacts on the rear

terminal board can be used to activate indicators or operate solenoid valves for

controlling temperature-related functions. A switch on the front panel permits

momentary display of the two setpoints.
