Industrial heat treatment Steel Metallurgy IR pyrometer

    Fiber optical Infrared Pyrometer is a kind of prometer. For the ordinary Infrared Thermometer, its main principle is to detect the surface temperature of the object by perceiving the infrared radiation emitted by the object itself in a non-contact way. For optical fiber 1-color pyrometer, the difference between it and ordinary infrared pyrometer is to transmit infrared to the sensor through the optical fiber, so that the optical path system and circuit system of the thermometer can be separated.

    Temperature measurement infrared pyrometer working principle of non-absolute zero objects will emit infrared, and infrared intensity and band changes with the temperature, through this principle, we can detect the surface temperature of the object as long as we can collect the infrared emission of the object.Based on this idea, various Industrial Pyrometer have been made. The basic principle is to focus the infrared radiation from the radiation source (the object being measured) on the sensor through a lens, converting the optical signal into an electrical signal, which is then converted into temperature through a series of processing.The fiber one color pyrometer transmits light through the optical fiber to the sensor, rather than focusing it directly from the lens to the sensor. The rest of the principle is the same as ordinary industrial infrared pyrometer.

    Compared with integrated monochromatic pyrometer, fiber optical infrared pyrometer has many advantages, the most important advantages are as follows: 1.Because the optical path system is separated from the circuit system, the optical path system of the thermometer can be installed in high temperature environment (200 degrees of field environment resistance) in the industrial field application, and can work stably online for a long time.Since the optical path system contains no electricity at all, the installed industrial site is completely explosion-proof.The circuit part of the thermometer can be installed indoors or far away from the high temperature scene, connected by optical fiber and optical road part, so as to completely avoid the interference of the high temperature of the temperature measurement scene to the instrument temperature measurement.2. Because the infrared signal of the Fiber optical pyrometer is transmitted to the sensor through the infrared fiber of special material, in this way, when the optical path is focused on the optical fiber, only the light spot size of the fiber section can be transmitted to the sensor through the optical fiber.In this way, the influence on the stability and service life of the sensor is avoided when the large area of light is directly focused on the sensor.And, the infrared fiber is made of special materials, you can only select the required infrared band through the fiber, so as to further weaken the light on the sensor baking.Therefore, the optical fiber infrared pyrometer has better stability and longer service life than the integrated 1C pyrometer.

 Monochromatic infrared pyrometer in the industrial application is very wide, the most used is mainly portable infrared thermometer and online infrared thermometer.At present, with the increasingly mature technology of optical fiber infrared pyrometer, and its advantages in the industrial scene are increasingly prominent, optical fiber 1-color pyrometer has begun to slowly replace the integrated infrared thermometer online temperature measurement, applied in various occasions in the industrial scene.
