Abstract

Provided is a temperature-difference temperature measuring device, comprising a liquidometer. The liquidometer is provided with a sensor array. The sensors in the sensor array comprise sensor probes. The sensor probe is provided with a heat conducting structure. The heat conducting structure comprises a flexible heat conducting layer, and the flexible heat conducting layer is adhered to a first heat conducting portion. The first heat conducting portion and a second heat conducting portion are connected through a connecting piece. The second heat conducting portion is connected with the sensor probes. Using the above structure, through installing the heat conducting structure on the sensor probe, the sensor probe indirectly contacts with an object heat source through the heat conducting structure, and the heat conducting structure ensures good heat conducting effect and effectively prevents generation of thermal contact resistance, and preferably ensures detection sensitivity of the sensors.

Description

technical field [0001] The invention relates to the field of industrial testing equipment, in particular to a temperature difference liquid level measuring device.
