The profiles of temperature sensor

Temperature sensor is * early development, * widely used type of sensor. The temperature sensor market share more than the other sensors. From the early 17th century people began to use temperature measurement. With the support of semiconductor technology, the century successively developed a thermocouple sensor, semiconductor PN junction temperature sensor and integrated temperature sensor. Correspondingly, according to the laws of the interaction between wave and material, successively developed acoustic temperature sensors, infrared sensor and microwave sensor. * of the temperature sensor is a variety of various sensors for a common, modern appearance of temperature sensor is very small, so more to make it widely used in the areas of production practice, also offers numerous benefits for people's life and function. The temperature sensor has four main types: thermocouple, thermal resistance, resistance temperature detector ( RTD) And the IC temperature sensor. IC temperature sensor and includes two types, that is, analog output and digital output. Conductor of two kinds of different materials, such as connected together, at some point of the heating connection, at the site of the they don't heat potential difference will occur. The potential difference value associated with the temperature of the heating part of points, and it has to do two conductor material. This phenomenon can be found in a wide range of temperatures, if * * measuring the potential difference, to measure the heating part of the environment temperature, can accurately know the temperature of the hot spots. Because it must have two different material of the conductor, so called 'thermocouple. Different material to make the thermocouple used in different temperature range, their sensitivity is also each are not identical. The sensitivity of thermocouple refers to add 1 ℃ hot spot temperature changes, the output variation of potential difference. For most of the metal material support thermocouple, this value about between 5 ~ 40 microvolt / ℃.
