<p>A temperature sensor includes an elongated cylindrical thermal body having a longitudinal bore therethrough. The body also has a first, closed, heat sensing end and a second, open end. At least one thermocouple is mounted within the bore of the thermal body heat conducting relationship with the heat sensing end and extends outwardly through the second end for connection to a signal measuring device. The heat sensing first end of the thermal body is provided with male threads for screwing the first end into a threaded cavity in metal surface such as a metal vessel wall. The thermal body at about its mid-section has a diameter greater than the diameter of the first end and is threaded around the circumference. The sensor includes a lock nut which screws over the mid section locking the thermal body to a vessel wall when it is screwed into the cavity provided in the wall to receive the heat sensing end.</p> |
