AI Technical Summary

Technical Problem

Existing temperature sensor units face challenges in accurately measuring the temperature of non-cylindrical objects, particularly plate-shaped measurement objects, due to the difficulty in achieving a configuration that is both easy to manufacture and ensures precise positioning of the sensor case relative to the object.

Method used

A temperature sensor unit design featuring a sensor case with specific side orientations and a holding member that integrates multiple contact points with the object, allowing for secure fixation and accurate positioning, even on non-cylindrical objects, while maintaining ease of manufacturing.

Benefits of technology

The design enables accurate temperature measurement of variously shaped objects by ensuring secure fixation and precise positioning of the sensor case, despite its simple manufacturing configuration.

Abstract

To provide a temperature sensor unit that is easy to manufacture and can accurately measure the temperature of an object being measured. [Solution] In the temperature sensor unit 2, the sensor case 20 extends in the Z-axis direction. The sensor case 20 houses the temperature sensor 10. The holding member 30 holds the sensor case 20. The sensor case 20 has an outer surface including a first side and a second side. The first side is aligned with the Z-axis direction. The second side is aligned with the Z-axis direction and extends in the Y-axis direction, intersecting with the first side. In the holding member 30, the first part is in contact with the first side. The second part is facing the second side. The third part is configured to be in contact with the corner 3f of the object to be measured 3. The holding member 30 is integrally constructed to surround the sensor case 20 when viewed from the first direction, and is located in the order of the second part, the first part, and the third part.
