Temperature sensor principle and application is introduced

Temperature sensor principle

temperature sensor using the physical law of various physical properties vary with temperature temperature conversion for the available output signal. The temperature sensor is the core part of the temperature measuring instrument, wide variety. According to measuring methods could be divided into two types: contact and non-contact, according to the sensor material and electronic component features divided into two categories, thermal resistance and thermocouple. Modern shape of temperature sensor is very small, so more to make it widely used in the areas of production practice, also offers numerous benefits to our lives and functions.

temperature sensor USES the

temperature is representing the degree of cold and hot objects physical quantities, is an important industrial and agricultural production process and common measuring parameters. Temperature measurement and control to ensure product quality, improve production efficiency, energy saving, production safety, and promote the development of the national economy plays a very important role. Because of the universality of temperature measurement, temperature sensor in various kinds of sensors in the first place, the number of about 50%.

temperature sensor is through the object with the temperature change and change some features to indirect measurement. A lot of material, features of components along with the change of temperature changes, so can the temperature sensor so many materials. Temperature sensor with temperature change caused by the physical parameters of are: expansion, resistance, capacitance, and electromotive force, magnetic energy, frequency, the optical properties and thermal noise and so on. With the development of production, the new type of temperature sensor will emerge.

temperature sensor and the contact way of measured medium is divided into two broad categories: contact and non-contact. Contact temperature sensor needs to maintain thermal contact with the measured medium, make sufficient both heat transfer and reach the same temperature. This kind of sensors are resistive, thermocouple, PN junction temperature sensor, etc. Non-contact temperature sensor without contact with the measured medium, but by the measured medium thermal radiation or convection to the temperature sensor, in order to achieve the purpose of temperature measurement. This kind of sensor are mainly infrared measuring temperature sensor. The main characteristics of the temperature measuring method can measure the temperature of the motion state of material.
