Front Load Dual Sensor

Overview

INFICON Front Load Dual crystal sensors offer proven reliability and durability and have the best thermal stability of any sensor head on the market. The dual sensor provides a backup crystal and is essential for critical processes where it is desirable to have the second crystal in the vacuum chamber.

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 in a sensor/feedthrough combination that can be either welded or assembled with compression fittings

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 inch (0.32cm) O.D. All shuttered sensors require the 750-420-G1 pneumatic control valve. Limited use with other controllers is possible call KJLC +1 800 245 1656 or click here to contact us with any technical questions.

NOTES

Orders for sensors welded to the feedthroughs should be requested with a length, in cm, between 20 and 99 cm. If another length is needed, please contact us by clicking here . Once special length or manufactured order is confirmed, it can not be canceled.
Sensor lengths are measured from center of the crystal to the vacuum side (sealing surface) of the feedthrough.
For sensors ordered without a weld connection (option "0" or "8"), tubes are made to a length of 29.75" (756mm) for "E" length and Cool Drawer sensors and 44.75" (1137mm) for "G" length sensors.
For sensors ordered with the Ultra Torr compression fittings, the length will be set to the maximum length (76 cm). This length can then be adjusted.

NOTES

Orders for a WELDED sensor/feedthrough combination are measured from center of the crystal to the vacuum side (sealing surface) of the feedthrough. Once a welded sensor order is confirmed, it cannot be canceled.
Feedthrough configuration varies depending on options selected (Front Load or Cool Drawer, with or without shutter, type of feedthrough, etc.). Example: SL-A0E37 uses feedthrough PN 002-042 while SL-A1E37 uses feedthrough PN 750-030-G1.
Front Load Dual sensors ordered with a CF40 feedthrough cannot be welded due to dimensional limits of the CF40.
For sensors ordered without a weld connection (option "0" or "8"), tubes are made to a length of approximately 76.2 cm (30")
Front Load Dual sensors welded to lengths between 28 and 34 inches will include a 36 inch in-vacuum cable. Sensors welded to lengths between 34 and 39 inches will include a 48 inch in-vacuum cable.
The following combinations are not available: (see notes 3 and 4): DL-AE47, DL-AG47, DL-AE38, DL-AG38 Examples of non-valid part numbers include all options with no feedthrough connection or compression fittings and a welded sensor length; for example, DL-AE40-20, DL-BE40-20, etc.
