Abstract
A multipoint thermocouple assembly using coil springs in which a coil spring is used with each thermocouple to maintain contact between the thermocouple measuring junction and the interior side of the assembly housing. Maintenance of such contact helps to insure an accurate reading of temperature changes which occur outside the assembly housing.
Claims6
In a thermocouple assembly for obtaining a temperature profile of a process throughout a vessel, which assembly includes a thermocouple having a cold junction and a temperature sensitive end, an enclosure containing said cold junction, a housing extending from the enclosure containing a longitudinal passage therein, the thermocouple being located in the longitudinal passage and extending generally parallel thereto throughout most of its length, the improvement comprising:
- a. the temperature sensitive end of the thermocouple extending generally perpendicular to the longitudinal passage and being in contact with the interior of the housing;
- b. a support strap located in said longitudinal passage and through which the temperature sensitive end of the thermocouple extends;
- and
- c. coil spring means operatively connected to the temperature sensitive end for maintaining said temperature sensitive end in contact with the interior of said housing.
In a thermocouple assembly for obtaining a temperature profile of a process throughout a vessel, the combination including:
- a. a thermocouple having a cold junction and a temperature sensitive end;
- b. an enclosure containing said cold junction;
- c. a housing extending from the enclosure and containing a longitudinal passage therein, the thermocouple being located in the longitudinal passage and extending generally parallel thereto throughout most of its length, while the temperature sensitive end of the thermocouple extends generally perpendicularly to the longitudinal passage and is in contact with the interior of the housing;
- d. a support strap located in said longitudinal passage and through which the temperature sensitive end of the thermocouple extends;
- and
- e. coil spring means operatively connected to the temperature sensitive end for maintaining said temperature sensitive end in contact with the interior of said housing.
