SENSING METHOD FOR CYLINDRICAL SURFACES

Provided herein is an apparatus and method for sensing the temperature of a tubing wall, and inferentially the temperature of a fluid within the tubing. The apparatus includes first and second clamp bodies, the first clamp body comprising a heat transfer element and a first and a second electrical connection connected thereto, the second clamp body connectable to the first clamp body to form a clamping cavity therebetween within which a clamped element having a wall is securable, the heat transfer element configured to contact an outer surface of a clamped element therebetween. The heat transfer element may include a thermally conductive compliant element extending through one of the clamp bodies and inwardly of the clamping cavity.
