    Description

    WRN-330 WRN-430 WRN-630 WRN-230 WRN-130 K thermocouples

    Product introduction:

    WRN-330 WRN-430 WRN-630 WRN-230 WRN-130 K thermocouples, infrared temperature sensor is a sensor that converts temperature into electricity using the laws of various physical properties of the material. The physical properties of these regular changes are mainly physical. The temperature sensor is the core part of the temperature measuring instrument. According to the measurement method, it can be divided into two types: contact and non-contact. According to the characteristics of the sensor material and electronic components, it can be divided into two types: thermal resistance and thermocouple.
    In the process of electric power production, temperature measurement and control are very important. Accurate measurement of temperature parameters is critical to the output quality of electric energy, production efficiency, and safe and reliable operation. At present, non-traditional temperature measurement sensors such as advanced infrared thermometers have gradually been used in the process of power production and maintenance to replace traditional thermocouples and thermal resistance type thermoelectric temperature sensors, thereby realizing the power production process or important equipment. Temperature monitoring and control.
    Principles and advantages of infrared temperature sensors
    Infrared sensing system is a measuring system using infrared as the medium. It can be divided into five categories according to its function, and can be divided into photon detectors and thermal detectors according to the detection mechanism. Infrared sensing technology has been obtained in the fields of modern technology, national defense, industry and agriculture. A wide range of applications
    Infrared radiation is commonly referred to as infrared, which refers to electromagnetic waves with a wavelength in the range of approximately 0.75-1000mm. The physical nature of infrared radiation is thermal radiation. When the temperature of an object is above absolute zero, the thermal movement of the charged particles inside it will emit infrared rays. The higher the temperature of an object, the more infrared radiation it emits, and the stronger the energy of infrared radiation. Infrared thermometers are based on the amount of infrared radiation energy of an object and its wavelength distribution, and the corresponding relationship with the surface temperature of the object. The infrared temperature of the object is measured to accurately determine the surface temperature of the object.
    Compared with conventional temperature sensors such as thermocouples and thermal resistors, infrared thermometers have many advantages such as a wide temperature range, long life, reliable performance, extremely fast response, and non-contact properties. In addition, the infrared thermometer is also particularly suitable for measuring the temperature of corrosive media and moving objects without destroying the temperature field of the measured object.
    In recent years, with the rapid development of microprocessor chips and infrared temperature sensing technology, the performance of infrared temperature sensors has been continuously improved, and its application range can already cover different sections of low, medium and high temperature.
    Low and medium temperature infrared temperature sensor in electrical facilities and process measurement and control
    Infrared pyrometers in furnace applications
    In general, infrared thermometers for measuring high temperature (above 700 ° C), its useful band is mainly in the near-infrared region of 0.76 ~ 3mm, and the optical materials used for transmission are mainly optical glass or quartz.
    Through the temperature of the boiler furnace and rear furnace area of the power plant, not only can it directly reflect the combustion intensity of the fuel in it, the efficiency of the combustion process, but also indirectly affect the heating surface of the boiler and subsequent processes (such as Denitration, ash control, etc.). From the perspective of power plant safety control and efficiency, the temperature in the furnace area is very important, and key parameters for operation monitoring are needed. In Europe, a considerable number of power plant or boiler manufacturers (such as French Stein boilers) use the above-mentioned infrared optical pyrometers to measure the flue gas temperature of large boiler furnace sections, and thereby achieve the full furnace Flame detection and furnace fire protection.
