Abstract
A strain-resistant resistance temperature element for a temperature averaging sensor and apparatus for producing same. Highly sensitive thin metal wire, typically of platinum, is attached to both sides of a high temperature, pliable yet stretch/strain resistant tape. A somewhat wider tape of similar description is then applied to both sides of the tape containing the sensor wire. As a result, a highly pliable, yet stretch/strain resistant resistance temperature detector is provided. The major advantages of the invention being that the resistance temperature detector (RTD) of the instant invention is provided substantial strain relief and, therefore, will overcome the problems of prior art sensors, which broke 100% of the time after a minimal period of use. Further, the RTD of the present invention may be pulled through the plastic tubing used to shelter the RTDs from the material being measured, without fear of breaking.
