Abstract
An apparatus for sensing the temperature of a fluid being drawn from a well includes a pipe having a wall, a sensor mounted on the outer surface of the pipe wall, an insulator, and a housing attached to the pipe that encloses the sensor and the insulator. The fluid to be sensed is drawn from the well through the pipe. The thermal conductivity of the pipe wall is greater than that of the insulator.
