Cool Drawer Dual Sensor
The Cool Drawer Dual Sensor is designed for use in critical processes where it is desirable to have a second crystal in the vacuum chamber. Water cooled, cast stainless steel sensor body, two Cool Drawer crystal holders and a pneumatically actuated shutter provide for a rugged sensor head with the extra reliability of a backup crystal. A cleaner, more reliable vacuum system installation is possible as there are no coaxial cables inside the chamber.
Use Part Finder to select sensor configuration.
FEATURES
- Dual crystals
- Cool Drawer crystal holder
- No internal cables
- Crystal shutter
- Available with: CF40 feedthrough and 2.54 cm (1 inch) bolt feedthrough
- Bakeable if ordered with welded CF40 flange
- Adjustable length if ordered with compression fittings
- Sensor/feedthrough combinations available welded to customer specified lengths
NOTE 1:
Orders for a WELDED sensor/feedthrough combination are measured from centre of the crystal to the vacuum side (sealing surface) of the feedthrough. Once a welded sensor order is confirmed, it can not be cancelled.
NOTE 2:
Feedthrough configuration varies depending on options selected (Type of feedthrough and connection).
Example: CDD-AF47 and -BF47 use a two-piece hybrid feedthrough design due to dimensional limits of a standard CF40.
NOTE 3:
For sensors ordered without a weld connection (option “8”), tubes are made to a length of approximately 76.2 cm (30 in.) for standard
Cool Drawer Sensors and approximately 66 cm (26 in.) for Right Angle Cool Drawer sensors.
NOTE 4:
Cool Drawer Sensors are not available without a feedthrough and must be either welded or connected with Ultra-Torr fittings.
