Development in recent years, a temperature sensor wholesale, China's industrial modernization process and the electronic information industry, continuous growth, temperature sensor manufacturers, led to the rapid increase 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 into electrical quantities, Lanzhou temperature sensor, which can accurately measure the temperature of the semiconductor device and automatic control. Temperature sensor uses a very broad, can be used as temperature measurement and control, temperature compensation, velocity, flow and velocity measurement, level indication, temperature measurement, ultraviolet and infrared light measurements, microwave power measurement is widely used in color televisions, PC color monitors, switching power supply, 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. A temperature sensor (temperature transducer) means able to feel the temperature and converted into a usable output signal of the sensor. Temperature sensor is a core part of the temperature measuring instruments, a wide variety. Press the measurement can be divided into contact and non-contact two categories, according to the characteristics of the sensor material and electronic components into RTD and thermocouple types. Detecting portion in contact with the measured object main classification temperature sensor has good contact, also known as the thermometer. Thermometer by conduction or convection thermal equilibrium, so that direct indication thermometer indicates the temperature of the measured object. Usually high measurement accuracy. Within a certain temperature range, the thermometer can also measure the temperature distribution inside the object. But for the moving body, small target or heat capacity is very small object will have a greater measurement error, commonly used in thermometers bimetal thermometer, glass liquid thermometer, pressure thermometer, resistance thermometer, thermistor and thermocouple and so on. They are widely used in industry, agriculture, commerce and other departments. In daily life, people often use these thermometers. As research cryogenic technology in national defense engineering, space technology, metallurgy, electronics, food, pharmaceutical and petrochemical sectors and the wider use of superconducting technology, measure temperatures below 120K has been developed cryogenic thermometer, such as low temperature gas thermometers, steam pressure thermometer, acoustic thermometer, paramagnetic salts thermometer, quantum thermometer, low thermal resistance and low temperature thermocouple and so on. Low temperature thermometer temperature sensing element requires small size, high accuracy, reproducibility and stability. A porous high silica glass carburizing carburizing sintered glass thermal resistance is a low-temperature thermometer temperature sensing element, it can be used to measure temperature in the range of 1.6 ~ 300K. _ Xinfeng temperature sensor works (certified) _ Lanzhou temperature sensor sensing provided by the Xinxiang City, Xinfeng purification technology Limited.
