What industries are infrared thermometers suitable for?
Due to the nature of infrared measurement, infrared is more used in industrial fields. Infrared thermometers are commonly used in the steel, glass and plastic industries. They are also widely used in preventive facilities.
iron industry
The steel industry uses thermometers because the products are in motion and the temperature is very high. A common steel industry application is that the temperature is a constant state where molten steel begins to transform into lumps. Reheating the steel to the same temperature is key to preventing it from deforming, and infrared thermometers are used to measure the regenerator's internal temperature. In high temperature rotary mills, infrared thermometers are used to confirm that the temperature of the product is within the rotational limits. In cooling mills, infrared thermometers monitor the temperature of the steel as it cools.
glass industry
In the glass industry, products are also in motion and are heated to very high temperatures. Infrared thermometers are used to monitor the temperature in the furnace. Hand-held sensors detect hot spots by measuring the outside. Measure the temperature of the molten glass to determine the appropriate furnace mouth temperature. In flat glass products, sensors detect temperature at every processing stage. The wrong temperature or too rapid temperature change can cause uneven expansion or contraction. For bottle and container products, the molten glass flows to a forehearth maintained at the same temperature. An infrared thermometer was used to detect the temperature of the glass of the forehearth. So it should be in proper state where it is exported. In fiberglass products, infrared sensors are used in the processing furnace to detect the temperature of the glass in the forehearth. Another use of infrared sensors in the glass industry is in the windshield manufacturing process.
Plastic Industry
In the plastics industry, infrared thermometers are used to avoid product contamination, to measure dynamic objects and to measure high temperature plastics. During the ejection of the blown film, temperature measurements to accommodate heating and cooling can help maintain the integrity of the plastic's tension and its thickness. During the ejection of the polished film, sensors help control the temperature to ensure product thickness and consistency. Sensors allow the operator to adjust extinguished heaters and cold rolls to ensure product quality while the sheet is being pressed out.
preventive maintenance
With a portable heat display system, maintenance personnel can identify potential or existing problems. For example: overheated engine coil windings, plugged cooling fins on transformers, poor capacitor contact, heat build-up in the cylinder head of the compressor. Any problems that are accompanied by an increase in temperature, or a temperature profile that is completely different from the ambient temperature, can be located using a portable thermal display system. In most cases, problems can be identified and corrected in time before the process is required to be stopped.
chemical industry
In the petrochemical industry, refineries use temperature display systems as part of routine preventive maintenance procedures. These procedures include monitoring of furnace processes and verification of thermocouple readings. In the furnace process inspection, the infrared display is used to detect the proportion of carbon accumulation in the heating surface tube. This buildup, known as coking, results in a higher firing rate in the furnace and also increases the tube temperature. Such high temperature conditions will reduce the life of the tube. Because this coking prevents the product from absorbing heat from the tube evenly. When using an infrared thermometer, we will find that the surface temperature of the tube in the junction area tends to be higher than the surface temperature of the tube in other areas.
