Cryo-Torr
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.
