Product Description
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 of 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 functions for people's lives. .
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.

Contact
The detection part of the contact temperature sensor has good contact with the measured object, also known as a thermometer.
The thermometer achieves thermal equilibrium through conduction or convection, so that the value of the thermometer can directly indicate the temperature of the measured object. Generally, the measurement accuracy is high. Within a certain temperature measurement range, the thermometer can also measure the temperature distribution inside the object. But for moving objects, small targets or objects with small heat capacity, larger measurement errors will occur. Commonly used thermometers include bimetal thermometers, glass liquid thermometers, pressure thermometers, resistance thermometers, thermistors, and thermocouples. They are widely used in sectors such as industry, agriculture, and commerce. People often use these thermometers in daily life. With the wide application of cryogenic technology in national defense engineering, space technology, metallurgy, electronics, food, medicine, petrochemical and other sectors and the research of superconducting technology, cryogenic thermometers measuring temperatures below 120K have been developed, such as cryogenic gas thermometers, steam Pressure thermometer, acoustic thermometer, paramagnetic salt thermometer, quantum thermometer, low temperature thermal resistance and low temperature thermocouple, etc. Low temperature thermometers require small size, high accuracy, good reproducibility and stability. The carburized glass thermal resistance made of porous high silica glass carburized and sintered is a kind of temperature sensing element of the low temperature thermometer, which can be used to measure the temperature in the range of 1.6 to 300K.
Contactless
Its sensitive components do not touch each other with the measured object, and it is also called a non-contact temperature measuring instrument. This kind of instrument can be used to measure the surface temperature of moving objects, small targets and objects with small heat capacity or rapid temperature changes (transient), and can also be used to measure the temperature distribution of the temperature field.
The most commonly used non-contact temperature measuring instrument is based on the basic law of black body radiation and is called a radiation temperature measuring instrument. Radiation thermometry includes the luminance method (see optical pyrometer), radiation method (see radiation pyrometer) and colorimetric method (see colorimetric thermometer). All kinds of radiation temperature measurement methods can only measure the corresponding luminosity temperature, radiation temperature or colorimetric temperature. Only the temperature measured for a black body (an object that absorbs all radiation and does not reflect light) is the true temperature. If you want to determine the true temperature of an object, you must correct the surface emissivity of the material. The surface emissivity of the material not only depends on the temperature and wavelength, but also on the surface state, coating film and microstructure, so it is difficult to accurately measure. In automated production, it is often necessary to use radiation temperature measurement to measure or control the surface temperature of certain objects, such as the steel strip rolling temperature, roll temperature, forging temperature and the temperature of various molten metals in the smelting furnace or crucible in metallurgy.
