Overview
INFICON Front Load Single crystal sensors offer proven reliability and durability and have the best thermal stability of any sensor head on the market. The front load design allows for easy insertion of the crystal holder in applications lacking sufficient room for side insertion. Assembled mechanically rather than soldered, parts can be replaced conveniently in the field, if necessary. Sensors can be ordered individually or with a sensor/feedthrough combination that can be either welded or assembled with compression fittings
One or more of these sensors should be purchased with each controller. Each sensor comes completely assembled and includes integral water tubes,in-vacuum coaxial cable (Front Load) or in-vacuum conduit (Cool Drawer), water tube bending tool, crystal snatcher (Front Load), and operating instructions. All air and water tubes (except the bakeable sensor) are 1/8" (0.32cm) O.D. All shuttered sensors require the 750-420-G1 pneumatic control valve. Limited use with other controllers is possible call KJLC +1 412 387 9200 or click here with any technical questions.
