Abstract

The invention discloses a heat collecting device for high-precision temperature sensor detection. The device comprises an installing disc and a red copper column located below the installing disc, a standard device insert tube and a sensor insert tube are arranged between the installing disc and the red copper column, the lower ends of the standard device insert tube and the sensor insert tube areboth inserted into the red copper column and are fixedly connected with the red copper column, the lower ends of the standard device insert tube and the sensor insert tube get close, the upper ends of the standard device insert tube and the sensor insert tube are fixedly connected with the installing disc and evenly distributed in the circumferential direction, the upper ends of the standard device insert tube and the sensor insert tube are exposed from the upper face of the installing disc, and an installing bolt is arranged on the installing disc. The heat collecting device has the advantages of being simple in structure, close to temperature collecting position, small in error and accurate in detection.

Description

technical field [0001] The invention relates to a heat collection device, in particular to a special heat collection device for high-precision temperature sensor detection. Background technique [0002] The temperature sensor needs to be tested with a standard device during detection. A liquid at a certain temperature is filled in a box, and a stirrer with blades is equipped in the box to ensure uniform temperature everywhere in the box. Insert the standard instrument and the temperature measuring end of the temperature sensor to be tested into the box through the upper cover of the box body, and then use the standard instrument to measure the temperature sensor. There will be a certain error in this way, mainly because the insertion ends of the standard device and the temperature sensor have a certain distance from each other, and the positions for collecting temperature signals are different. Contents of the invention [0003] The purpose of the present invention is to ...
