Applications of Infrared Thermometers in Industry
Infrared temperature measurement technology plays an important role in product quality control and monitoring, online fault diagnosis and safety protection of equipment, and energy conservation in the production process. In the past 20 years, non-contact infrared human body thermometers have developed rapidly in technology, with continuously improved performance, enhanced functions, increasing varieties, and expanding applicability. Compared to contact based temperature measurement methods, infrared temperature measurement has advantages such as fast response time, non-contact, safe use, and long service life. Non contact infrared thermometers include three series: portable, online, and scanning, and are equipped with various options and computer software. Each series also has various models and specifications. Choosing the correct infrared thermometer model is crucial for users among various types of thermometers with different specifications.
1, Infrared thermometers in the steel industry
The steel industry uses thermometers because the products are in motion and the temperature is very high. The ordinary application in the steel industry is that the temperature is a continuous state, and the melted steel begins to transform into blocks. The key to preventing deformation of steel is to reheat it at the same temperature, and infrared thermometers are used to measure the internal temperature of the reheater. In high-temperature rotary mills, infrared thermometers are used to confirm that the temperature of the product is within the rotation limit. In the cooling rolling mill, infrared thermometers are used to monitor the temperature of steel during the cooling process.
2, Infrared thermometers in the glass industry
In the glass industry, it needs to be heated to very high temperatures. Infrared thermometers are used to monitor the temperature in furnaces. Handheld sensors detect high temperature points by measuring the external environment. Measure the temperature of melted glass to determine the appropriate temperature at the furnace mouth. In flat glass products, sensors need to detect temperature at each processing stage. Incorrect temperature or rapid temperature changes can cause uneven expansion or contraction. For bottle and container products, the melted glass will flow towards the front furnace maintained at the same temperature. Infrared thermometers are used to detect the temperature of the glass in the front furnace. So it should be in an appropriate state at the exit. In fiberglass products, infrared sensors are used to detect the temperature of the glass in the front furnace during processing. Another use of infrared sensors in the glass industry is in the production process of windshield products.
3, Infrared thermometer for chemical industry
In the petrochemical industry, refineries use temperature display systems in their routine preventive maintenance procedures. These programs include monitoring of furnace processes and confirmation of thermocouple readings. In furnace process testing, infrared displays are used to detect the proportion of carbon accumulation in the heated surface tubes. This type of agglomeration, known as coking, leads to a higher ignition rate in the furnace and also increases the temperature of the pipes. This high temperature condition will reduce the lifespan of the pipes. Because this coking will hinder the product from uniformly absorbing the heat from the tube. When using an infrared thermometer, we often find that the surface temperature of the pipes in the contact area is higher than that in other areas.
4, Infrared thermometers in the plastic industry
In the plastic industry, infrared thermometers are used to prevent product contamination, measure dynamic objects, and measure high-temperature plastics. During the spraying process of blown film, temperature measurement to adjust for heating and cooling can help maintain the integrity of plastic tension and its thickness. During the process of spraying the film, sensors help control the temperature to ensure the thickness and consistency of the product. During sheet extrusion, sensors allow operators to adjust the extinguished heater and cold coil to ensure product quality.
