Application temperature sensor is the first development, the most widely used class of sensors. Market share is much higher than the temperature sensor other sensors. From the early 17th century people began using the temperature measurement. In support of semiconductor technologies, this century have developed a semiconductor thermocouple sensor, PN junction temperature sensor and integrated temperature sensor. Two conductors of different materials, temperature sensor wholesale, such as connecting with each other at some point, the temperature sensor price for this junction is heated, unheated parts in their potential difference occurs. The potential difference of the value of the temperature unheated parts of the measuring point is related to the two conductors and related materials. This phenomenon can be used over a wide temperature range appears, if accurate measurement of the potential difference, Shandong temperature sensor, and then measure the unheated parts of the ambient temperature, it is possible to accurately know the temperature of the heat spots. Because it must have two conductors of different materials, so called "thermocouple." Thermocouples made of different materials used in different temperature ranges, their sensitivity varies. Thermocouple sensor has its own advantages and disadvantages, it is relatively low sensitivity, susceptible to environmental interference signal, but also susceptible to temperature drift of the preamplifier, therefore not suitable for measuring small temperature changes. Due to the thickness of unrelated pt100 temperature sensor sensitivity and materials thermocouple temperature sensor is a temperature variable into a standardized output signal can be transmitted instrument. Mainly used for industrial process measurement and control temperature parameters. Transmitters with sensors usually consist of two parts: a sensor and signal converter. Sensors are mainly thermocouples or RTD; signal converter mainly by the measurement unit, signal processing and conversion units (due to industrial heat resistance and thermocouple indexing table is standardized, so the signal converter is also known as a standalone product transmitter), an increase of some transmitter display unit, some also have fieldbus function.
