Four types.
There are four main types of temperature sensors. : Thermocouples, thermistors, and resistance temperature detectors (RTD) and NTC Temperature sensor.
Thermocouple sensor
A thermocouple is a temperature-sensing element and an instrument that directly measures temperature and converts the temperature signal into a thermoelectric potential. This potential is then processed by electrical instruments to determine the temperature of the measured medium. The fundamental principle of thermocouple temperature measurement is that two conductors made of different materials form a closed circuit; when a temperature gradient exists between their junctions, a current flows in the circuit, and an electromotive force develops across the junctions—this phenomenon is known as the Seebeck effect. .
Thermistor sensor
The primary component of a thermistor sensor is the thermistor. When thermal radiation strikes the thermistor material, it absorbs the radiant heat, causing its temperature to rise and resulting in a change in the material’s resistance.
Resistance Temperature Detector
RTD Typically, platinum, copper, or nickel are used; the electrical resistance of these metals… - The temperature relationship is shown in the figure, and their temperature coefficients are relatively large. , It exhibits a rapid response to temperature changes, is resistant to thermal fatigue, and is easy to process and fabricate into precision coils.
IC Temperature sensor
Integrated sensors are fabricated using silicon semiconductor integration technology, and are therefore also referred to as silicon sensors or monolithic integrated temperature sensors. Analog integrated temperature sensors are… 20 Century 80 It was introduced in the [year], and is a dedicated device that integrates a temperature sensor onto a single chip, capable of performing temperature measurement and providing analog signal output. IC The main characteristics of analog integrated temperature sensors include single-functionality, low measurement error, low cost, fast response, long transmission distance, compact size, and ultra-low power consumption. They are well suited for long-distance temperature measurement and control, require no nonlinear calibration, and feature a simple external circuitry.
