Front Load Single Sensor
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 in a sensor / feedthrough combination that can be either welded or assembled with compression fittings.
Features
- Front load crystal holder
- Easy installation
- Available with 2.54 cm (1 inch) bolt feedthrough / CF40 Feedthrough
- Adjustable length if ordererd with compression fittings
- Sensor / Feedthrough combinations available welded to customer specified lengths
- No brazing required if ordered with compression fittings or welded to feedthrough
