Temperature sensor by an object with temperature change certain characteristics measured indirectly. Many materials are characteristic of the element changes with temperature changes, the temperature sensor wholesale, so the material can be considerable temperature sensor. Temperature sensor with temperature changes caused by the physical parameters are: expansion, resistors, capacitors, and the electromotive force, magnetic, frequency, optical characteristics and thermal noise and the like. With the development of production, Wuhu temperature sensor, the new temperature sensor will continue to emerge. Since the industrial and agricultural production in an extremely wide temperature measurement range from several hundred degrees below zero to thousands of degrees above zero, a temperature sensor prices, and a temperature sensor made of various materials can only be used within a certain temperature range. -Contact temperature sensor with the measured medium is divided into two categories: contact and non-contact. The need to maintain contact temperature sensor in thermal contact with the measured medium, so that the two heat exchange sufficient to achieve the same temperature. This type of sensor are mainly resistive, thermocouple, PN junction temperature sensor. Non-contact temperature sensor without contacting with the measured medium, but by thermal radiation measured media or spread to a temperature sensor in order to achieve the purpose of temperature. This type of sensor main infrared sensors. The main feature of this method is that it can measure the temperature Temperature motion state of matter (such as the exercise of a slow train bearing temperature, rotating cement kiln temperature) and thermal capacity of small objects (such as an integrated circuit temperature distribution).
