Germanium sensor package and mounting adapter

Germanium packages and adapters allow the sensor to be soldered in place, screwed on, bolted down, inserted into a hole, or inserted through a pressure seal in the form of a thermowell. Appendix C Sensor Packaging and Installation discusses techniques for correctly installing cryogenic temperature sensors. Special packaging is also available—consult Lake Shore for custom orders.

Additional information about Lake Shore sensors and packaging can be found in our Temperature Sensor Selection Guide.

Each sensor package or adapter has been rated for four attributes or characteristics. These ratings give a general idea of how a package will perform and aid in the early decision-making process but are not a substitute for detailed specifications.
