Temperature probe calibration applications

temperature probe calibration is the first development, the most widely used class of sensors. Temperature probe calibration market share greatly exceeded the 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 storage tank calibration methods and integrated temperature probe calibration.
Two conductors of different materials, such as connecting with each other at some point, the connection point of heating in their unheated parts of the 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, and then measuring 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 the thermocouple temperature probe calibrated sensitivity is independent of the material

Temperature probe calibration

Thermocouple consists of two different conductors (hot electrode), with their ends are welded to each other to form a measuring end of the thermocouple (also known as the working end). Insert it into the measured temperature of the medium; and the other end of the tank calibration software is connected to the display instrument. If the measuring end of the thermocouple and reference junction temperature difference, the indicator will indicate the thermocouple heat generated by the electromotive force.
Thermocouple temperature probe calibration generally or RTD, thermocouple temperature changes voltage change, there is resistance heat resistance temperature change, that is the good. Applications: thermometer accessories, probes.

Temperature probe calibration

Temperature probe calibration means can feel the temperature and converted into usable output signal of the sensor. temperature probe calibration 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, in recent years, China's industrial modernization process and the electronic information industry, continuous growth, led to the rapid increase in the sensor market. Ttank calibration software as a sensor important category, accounting for over 40% of the total demand of the sensor. NTC temperature probe calibration is the use of resistance varies with temperature characteristics of the non-electrical quantities converted into electrical quantities, which can accurately measure the temperature of the semiconductor device and automatic control. Temperature probe calibration uses a very broad, can be used as temperature measurement and control, temperature compensation, velocity, flow and velocity measurement, level indication, temperature measurement, measurement of ultraviolet and infrared light, microwave power measurement is widely used in color televisions , computer color display, 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 probe  calibration.
