If you choose to be a reliable method for temperature measurement, first you need to select the correct temperature meter, which is the temperature sensor. Wherein thermocouples, thermistors, platinum resistance (RTD) and test temperatures are most commonly used in IC temperature sensor. Thermocouple temperature measurement is the most commonly used temperature sensor. Its main advantage is a wide temperature range and adapt to the atmosphere, and the strong, the lowest temperature sensor, no power supply, but also the cheapest. Is composed of two different thermocouple wire is connected at one end (the metal A and metal B) constituting the temperature sensor manufacturer, when heated at one end of the thermocouple, the thermocouple circuit have a potential difference. Measuring the potential difference can be used to calculate the temperature. However, among non-linear relationship between voltage and temperature is a temperature sensor price, due to the temperature is non-linear relationship between voltage and temperature, and therefore need to reference temperature (Tref) for the second measurement, and the use of test equipment software or hardware in the processing within the instrument voltage - Temperature transformation to finally get the thermocouple temperature (Tx). Agilent34970A and 34980A data acquisition system has a built-in measuring the computing power. In short, the thermocouple is the simplest and most common temperature sensors, thermocouples, but not suitable for high-precision measurement and application. Development in recent years, China's industrial modernization and continuous electronic information industry growth, led to the rapid rise in the sensor market. Temperature sensor as a sensor in an important category, accounting for more than 40% of the total demand of the entire sensor. NTC temperature sensor is the use of resistance varies with temperature characteristics of the non-electrical quantities converted to electrical quantities, which can accurately measure the temperature of the semiconductor device and automatic control. Temperature sensor uses a very broad, can be used to measure and control temperature, temperature compensation, velocity, flow and wind speed measurement, level indication, temperature measurement, ultraviolet and infrared light to measure the microwave power measurements are widely used in TV, PC color monitors, switching power, water heater, refrigerator, kitchen equipment, air conditioning, automotive and other fields. In recent years, the rapid growth of automotive electronics, consumer electronics industry led to the rapid growth of China's demand for temperature sensors.
