The application of the on-line infrared thermometer
1. Infrared thermometer 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 can be adjusted to adapt to heating and cooling, which can help maintain the integrity of plastic tension and its thickness. During the spraying process of the cast film, sensors help control the temperature to ensure the thickness and consistency of the product. When the thin film is pressed out, the sensor allows the operator to adjust the extinguished heater and cold coil to ensure product quality.
2. Infrared thermometer in the glass industry
In the glass industry, it needs to be heated to a very high temperature. Infrared thermometers are used to monitor the temperature in the furnace. The handheld sensor detects high temperature points by measuring the external environment. Measure the temperature of melted glass to determine the appropriate furnace temperature. In flat glass products, sensors need to detect temperature at each processing stage. Incorrect or rapid temperature changes can cause uneven expansion or contraction. For bottle and container products, 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 processing furnace. Another use of infrared sensors in the glass industry is in the production process of windshield products.
3. Infrared thermometer chemical industry
In the petrochemical industry, refineries use temperature display systems in routine preventive maintenance procedures. These programs include monitoring of the furnace process and confirmation of thermocouple readings. In furnace process testing, infrared displays are used to detect the proportion of carbon buildup on the heating surface tubes. This type of agglomeration, known as coking, can lead to a higher ignition rate in the furnace and also cause an increase in tube temperature. This high-temperature working condition will reduce the lifespan of the pipe. Because this type of coking will hinder the product from evenly absorbing heat from the pipes. When using an infrared thermometer, we will find that the surface temperature of the pipes in the junction area is often higher than that of the pipes in other areas.
4. Infrared thermometer in the steel industry
The steel industry uses thermometers because 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 molten steel begins to transform into blocks. Reheating steel at the same temperature is the key to preventing its deformation, and infrared thermometers are used to measure the internal temperature of the reheater. In high-temperature rotary rolling machines, infrared thermometers are used to confirm that the temperature of the product is within the rotational limit. In the cooling mill, infrared thermometers are used to monitor the temperature of steel during the cooling process.
5. Infrared thermometers can also provide preventive maintenance
With a portable heat display system, maintenance personnel can identify potential or existing issues. For example, overheating of the engine coil winding, clogged cooling fins on the transformer, poor capacitor contact, and heat accumulation in the cylinder head of the compressor. Any problem arises with an increase in temperature, or the temperature curve is completely different from the surrounding temperature, which can be located using a portable heat display system. In most cases, problems can be identified and corrected in a timely manner before requesting the cessation of the process flow.
