The SA1-RTD is a surface temperature sensor that can be applied to most clean, dry surfaces. Just peel off the release sheet on the bottom of the sensor and the silicone adhesive bonds the sensor to the surface, no cements or epoxies to mix, apply and cure.

The thin design of the SA1-RTD minimizes the effects of having the sensor attached to the surface of interest. Containing a thin film platinum sensing element, the SA1-RTD resistance is not affected by mounting to curved surfaces. With a fast thermal response time, the SA1-RTD will quickly respond to changes in temperature for fast, reliable measurements.
