Surface temperature sensor

Abstract

The invention belongs to the technical field of temperature sensors, in particular to a surface temperature sensor, which comprises a cylinder. The top end of the cylinder is rotationally connected with a chassis; a through hole is formed in the chassis; a driving motor is fixed at the through hole; a first gear is fixed to the output shaft end of the driving motor; a circular ring is rotationallymounted in an inner cavity of the cylinder; a gear ring is arranged on the inner side wall of the circular ring; the first gear is meshed with the gear ring; a push rod motor and a guide rail are fixed to the inner side wall of the circular ring; a sliding block is movably installed on the guide rail; the guide rail and the sliding block are each of an arc-shaped structure; the guide rail and thesliding block are concentric; and the circle center of the moving track of the sliding block is concentric with the circle center of the sliding block. According to the invention, the infrared temperature sensor is driven to rotate, and the angle of the infrared temperature sensor is adjusted, so that the measuring point of the infrared temperature sensor is located on the measuring point of themeasuring piece, the tracking measurement of the rotating body is realized, and the application range of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of temperature sensors, in particular to a surface temperature sensor. Background technique [0002] A temperature sensor is a sensor that senses temperature and converts 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 measurement method, it can be divided into two categories: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, it can be divided into two types: thermal resistance and thermocouple. [0003] Infrared temperature sensors are sensors that use the physical properties of infrared rays to measure. Infrared ray, also known as infrared light, has properties such as reflection, refraction, scattering, interference, and absorption. Any substance, as long as it has a certain temperature (above absolute zero), can radiate infrare...

Problems solved by technology

Therefore, even when the temperature sensor is installed on the product to be installed, the detection target range of the temperature sensor can be kept constant, and the quality can be maintained more stable. However, the temperature measurement can only be performed on objects at fixed positions. And rotating machinery or equipment cannot be tracked and measured, so the limitations are relatively large. Accordingly, the present invention proposes a surface temperature sensor
