What is the life expectancy in a heat cycling application with 50 psi applied?

Thank you for your inquiry Bob58. These probes are not pressure rated and they have not been tested on pressurized environments. We do not recommend the use of this probe in pressure environments. Life expectancy for any of our of products depends on the frequency the product is used.

Why do you say that the product is not suitable for application underwater? Is it an issue of the effect of having the water as a heat sink? Is it an issue of the thermocouple not being sealed in the polyimide material? Or the adhesive?

Thank you for your inquiry. Thermocouple is not sealed. When water is trapped inside the insulation after being submerged then the thermocouple will being to short out and give an intermittent incorrect millivolt output.

What is the accuracy of SA1-K thermocouples?

Thank you for your inquiry EngTester. The accuracy of SA1-K thermocouple is +/- 1.1°C or 0.4% whichever is greater.

Does the adhesive contain silicone?

The PSA is a Silicon based adhesive

Are these thermocouples suitable for an outdoor application? Specifically installation on the back of a solar panel for extended periods of time (> 6 months).

Yes, I have used these for that exact application with some Kapton tape on the TC and they work well.
