Abstract

This thermocouple assembly 1 measures the temperature of a thin part by contacting its edge 2 (dashed lines). The assembly is generally pivotally connected to a holding frame 3 to provide rotatable adjustment in contacting the edge 2 of the part. A contacting member 4 and thermo-couple elements 5 include projections that form a scissors-like contiguous relationship with the edge of the part.

Scissors Thermocouple

This thermocouple assembly 1 measures the temperature of a thin part by contacting its edge 2 (dashed lines). The assembly is generally pivotally connected to a holding frame 3 to provide rotatable adjustment in contacting the edge 2 of the part. A contacting member 4 and thermo-couple elements 5 include projections that form a scissors-like contiguous relationship with the edge of the part.

The contacting member 4 is rigidly affixed to the assembly. A shaft 6 is journaled to the contacting member. The thermocouple elements 5 are pivotally mounted on the shaft and electrically insulated from the shaft 6 and the contacting member 4 by insulating washers 7. A leaf spring 8, fastened to the contacting member by screw 9, limits the rotation of the thermocouple elements 5 while resiliently biasing these elements against the edge of the member contacted by the assembly. The biasing permits better electrical contact with the member. The contacting edges of the thermocouple elements 5 and the contacting member 4 can be sharpened to a knife edge, if desired for positive contact.

The thermocouple elements 5 are suitably, electrically connected by wires to a meter calibrated according to the material used for the thermocouple elements in the well known manner.
