Problems solved by technology

[0005] Whether it is a thermal resistance or a thermocouple sensor, the temperature signal is converted into an electrical signal to reflect the temperature information. Because of this, the use of the existing temperature sensor is greatly affected by the transmission of the electrical signal. In terms of use subject to great restrictions

Abstract

The invention relates to a temperature detection structure, which includes a main body, on which an optical fiber perforation is arranged, and the optical fiber perforation is divided into a first hole segment, a second hole segment, a third hole segment, the first hole segment, the second hole segment The three hole sections are holes with an elliptical radial section, and the second hole section is a hole with a circular radial section; the axial sections of the first hole section and the third hole section are right-angled trapezoidal, and the first hole section 1. The third hole section is arranged at both ends of the second hole section, and one end of the upper bottom of the right-angled trapezoidal axial section is connected with the second hole section; the temperature detection structure overcomes the existing temperature sensor because the temperature signal is directly The defect is converted into an electrical signal for detection, and due to the fast transmission rate of light, the temperature detection structure has better sensitivity, stronger real-time performance, simple design structure, and is convenient for long-distance temperature detection.

Description

technical field [0001] The invention relates to the technical field of temperature detection, in particular to a temperature detection structure. Background technique [0002] A temperature transducer is a sensor that can sense temperature and convert it into a usable output signal. The temperature sensor is the core part of the temperature measuring instrument, and there are many varieties. According to the characteristics of sensor materials and electronic components, it is divided into two types: thermal resistance and thermocouple. [0003] The thermal resistance is that the resistance value of the metal changes with the temperature change. For different metals, every time the temperature changes by one degree, the resistance value changes differently, and the resistance value can be directly used as an output signal. Thermal resistance is divided into two types of change: positive temperature coefficient and negative temperature coefficient. [0004] A thermocouple ...
