ABSTRACT:
A thermometer unit for monitoring the temperature of a fluid cooled electric transformer, the unit having a ceramic body insertable between the coils of the transformer winding immersed in cooling fluid in the transformer case. A nylon element responsive to heat changes is confined in the interior of the body and is adapted to expand according to developing heat changes. A flexible tubing having a loop portion fronting a tapered end of the nylon element is filled with a fluid which is caused to oscillate in the tubing accordingly as a rocker arm alternate actuates a pair of associated bellows. As the nylon element expands in response to a temperature rise, it squeezes the tubing causing a load to be placed upon the rocker arm which is indicative of the corresponding temperature change.
