Monitoring and regulating temperature is the basis of life, and creating technology to achieve this has always been the work of many scientists in history. Galileo invented the first thermometer recorded in the case in 1592, using a simple air system in a glass ball. It was not until the 18th century that Gabriel Wallen Hait invented more accurate mercury thermometers, and Anders introduced the calibration reference of 0-100 degrees today we know today.
Fast for hundreds of years. We now have thousands of advanced temperature sensors that use different technologies and design to achieve countless applications. Inventions such as thermistor , thermocouples , thermal electric piles, digital sensors, and platinum sensors have provided extensive benefits for different situations and environments. They have become ubiquitous and complicated devices in our daily life; from our coffee pots to traffic solutions, to office equipment, everything uses a certain type of temperature sensor.
The temperature sensor market is worth $ 5.13 billion in 2016, and it is expected to increase to $ 6.26 billion by 2022. This rapid growth comes from changes in consumers and industrial trends and technological changes. For example, in high -tech vehicles and semiconductor industries, advanced temperature sensors need to better run their production facilities, such as energy efficiency and automation process control.
thermal resistance temperature sensor
Thermistor sensor meets people's growing demand for high -efficiency, low -cost sensors. For thermal material, its resistance decreases with the rise of temperature. It is very sensitive to temperature changes and will not cause a large heat load. In addition, although NTC thermistor is small, they can work between -150 ° C and + 300 ° C, which is useful in many fields.
They are used for medical equipment, such as dialysis equipment, DNA sequencers and blood analyzers, as well as home appliances, such as stoves. One of its key applications is in the automotive industry, where it monitors external or internal temperature. In electric vehicles, preventing the battery from overheating is a fairly new requirement.
Thermocouple temperature sensor
Thermocouple sensor is light, connected to one point from two different metal wires. When one end is exposed to the source of the heat, the potential difference will occur.
The measured voltage uses this measuring voltage to calculate the temperature and activate the HVAC device, for example, to adjust the ambient temperature. The core benefit of the thermocouple sensor is that it can be used in very high temperature conditions or harsh environments, and the working temperature of some models is as high as 1800 degrees Celsius.
