Packages and adapters for platinum RTDs 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.
Some applications require more protection for your sensors (especially if they have to be immersed in liquid). Cryogenic temperature probes are great for those. Encased in a stainless steel thermowell fixture, the sensor can perform as designed, unaffected by high pressure and sealed to keep electrical components and wiring protected from fluids and other elements.
- Stainless steel-encased probes that provide high-reliability sensor performance in a thermowell
- Sealed to keep electrical components and wiring protected from fluids
- Ideal for temperature measurements in fluid containers and tanks
- Hermetic feedthrough at the end
- Also beneficial for extended sensor reach in narrow spaces
- Available in standard lengths up to 28 in (0.7 m) long
- Custom lengths and configurations are also available
