Advantages of Fiber Optic Infrared Thermometers
Fiber optic infrared thermometer is a type of infrared thermometer. Also known as fiber optic sensing thermometer, for ordinary infrared thermometers, its main principle is to detect the surface temperature of an object by sensing the infrared emitted by the object itself in a non-contact manner. The difference between fiber optic infrared thermometers and ordinary infrared thermometers is that they transmit infrared radiation to the sensor through optical fibers, which separates the optical and electrical systems of the thermometer.
1. Due to the separation of the optical system and circuit system, the optical system of the thermometer can be installed in high-temperature environments (able to withstand up to 200 degrees Celsius in the field environment) and can work stably online for a long time when applied in industrial fields. Due to the complete lack of electricity in the optical system, the industrial site where it is installed is completely explosion-proof. The circuit part of the thermometer can be installed indoors or away from high-temperature sites, connected through optical fibers and optical paths, thus completely avoiding the interference of high temperatures on the instrument's temperature measurement.
2. Due to the fact that the infrared signal of the fiber optic infrared thermometer is transmitted to the sensor through a special material infrared fiber, when the optical path is focused on the fiber optic, only the spot size of the fiber optic cross-section can be transmitted to the sensor through the fiber optic. This avoids the impact of large areas of light directly focusing on the sensor and baking it, which can affect the stability and lifespan of the sensor. Moreover, the infrared fiber is made of special materials, which allows only the required infrared band to be selected through the fiber, further reducing the baking effect of light on the sensor. Therefore, compared to integrated infrared thermometers, light infrared thermometers have better stability and longer service life.
