Brake Thermocouples
This versatile design is for measuring brake disc and drum temperatures. It consists of a 1/8” diameter X 1/8” long copper “slug” with the thermocouple wires silver brazed inside. It is available in any calibration and typically with 22 awg-stranded wire fiberglass insulated. On special order, it is also available in 1/16” and ¼” diameters and can be furnished isolated from the copper tip to provide an ungrounded version for high noise applications.
This is the T52 style with OB in the position 1 and 2 of the part number.
Rubbing Thermocouples
A spring loaded brake type thermocouple is mounted in a ½ inch diameter Stainless Steel tube with double nuts for mounting. It can rub against a moving part to provide surface temperatures with repeatable results to cancel the effects of friction. It is available in Type J or K calibration and can be provided ungrounded.
