Fatigue resistant thermowell and methods

A compressor comprising:

• a thermowell configured to enter a wall of the compressor along which a medium flows;
• an elongated probe of a thermocouple provided and configured to measure a temperature;
• at least one o-ring disposed on and in contact with the elongated probe section of the thermocouple at a first end, the o-ring being configured to dampen a vibration for the thermocouple by contacting the thermowell, wherein the contact between the o-ring and the elongated probe section is loose, such that a dampening fluid is able to flow passed the o-ring and into the thermowell;
• and
• an elastomer disposed around the elongated probe section of the thermocouple at a second end, the elastomer being configured to dampen the vibration for the thermocouple by contacting the thermowell;
• an intake section being configured to receive the medium;
• a shaft and rotor assembly configured to rotate and initiate compression of the medium received from the intake section;
• and
• an outlet section being configured to discharge the compressed medium.

A method for dampening vibrations of a thermocouple system, the method comprising:

• providing an elastomer in a housing piece, wherein the elastomer surrounds a first end of an elongated probe section of the thermocouple, and wherein the elongated probe section of the thermocouple is configured to measure a temperature of a medium contacting the thermocouple system;
• disposing at least one o-ring on and in contact with a second end of the elongated probe section of the thermocouple;
• disposing a dampening fluid within a housing of a thermowell in which the elongated probe section of the thermocouple is provided;
• and
• inserting the elongated probe section of the thermocouple into the thermowell, wherein the elastomer, the at least one o-ring and the dampening fluid reduce vibrations of the thermocouple, and wherein the contact between the o-ring and the elongated probe section is loose, such that the dampening fluid is able to flow passed the o-ring and into the thermowell.
