Thermowell adapter

A temperature probe with adapter for use with a thermowell, comprising:

• a sheathed and flanged temperature probe comprising:
• a temperature probe extending on an axis and having a sensing element received with a cylindrical sheath;
• a flanged extending perpendicular to the axis;
• and
• a reinforced section on the sheathed and flange temperature probe extending axially along the cylindrical sheath off the flange, the reinforced section having at least one extension so as to provide a non-cylindrical profile;
• and
• a thermowell adapter comprising:
• a body which has external threading for receipt in an internally threaded thermowell;
• a passageway defined within the body, the passageway defining an axis coaxially with the external threading, the passageway for receiving the cylindrical sheath of the temperature probe therethrough such that a sensing element of the temperature probe extends into the thermowell;
• and
• a recess open to the passageway, the recess providing a non-cylindrical profile for receiving the extension on the reinforced section of the temperature probe such that the extension received in the recess prevents the temperature probe from rotating about the axis.

A method of attaching a temperature probe into an internally threaded thermowell, comprising:

• screwing a thermowell adapter into the thermowell, the thermowell adapter comprising:
• a head;
• a body off the head which has external threading for receipt in the internally threaded thermowell;
• a passageway defined within the head and body, the passageway defining an axis coaxially with the external threading,
• a recess defined within the thermowell adapter;
• and
• an axial securement on the head;
• inserting a temperature probe into the passageway, the temperature
• probe comprising:
• a sensing element;
• a cylindrical sheath about the sensing element and extending along an axis;
• and
• at least one extension so as to provide a non-cylindrical profile;
• the temperature probe being inserted a sufficient amount such that the sensing element of the temperature probe extends into the thermowell and such that the extension mates with the recess of the thermowell adapter, the mating of the extension with the recess of the thermowell adapter preventing the temperature probe from rotating about the axis;
• and
• releasably securing the axial securement to thereby prevent the temperature probe from moving axially in the passageway.
