Latest company news about Introduction to temperature sensor

Temperature sensor refers to 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 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. The temperature sensor is the earliest developed and most widely used type of sensor. The market share of temperature sensors greatly exceeds that of other sensors. From the beginning of the 17th century, people began to use temperature for measurement. With the support of semiconductor technology, semiconductor thermocouple sensors, PN junction temperature sensors and integrated temperature sensors have been developed in this century. Correspondingly, according to the law of interaction between waves and matter, acoustic temperature sensors, infrared sensors and microwave sensors have been developed one after another.

The temperature sensor is the most commonly used one among the various sensors. The modern temperature sensor has a very small appearance, which makes it widely used in various fields of production practice, and also provides countless conveniences and conveniences for people’s lives. Function.
There are four main types of temperature sensors: thermocouples, thermistors, resistance temperature detectors (RTD) and IC temperature sensors. IC temperature sensor also includes two types of analog output and digital output. Dear customer: Thank you for your attention to our products.
