How infrared thermometers are applied in different fields of industry
Infrared thermometers for the 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 outside. Measure the temperature of the molten glass to determine the proper furnace mouth temperature. In flat glass products, sensors detect the temperature at every processing stage. 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. Infrared thermometers are used to detect the temperature of the glass in the forehearth. So it should be in the 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 process of windshield products.
Infrared thermometers for the plastics industry
In the plastics industry, infrared thermometers are used to avoid product contamination, measure dynamic objects and measure high temperature plastics. Temperature measurements to adjust for heating and cooling during blown film extrusion can help maintain the integrity of the plastic's tension and its thickness. During ejection of cast film, sensors help control temperature to ensure product thickness and consistency. During sheet extrusion, sensors allow the operator to adjust the heaters and cold coils to be turned off to maintain product quality.
Preventive Maintenance of Infrared Thermometers
With a portable thermal display system, infrared thermometer maintenance personnel can identify potential or existing problems. For example: overheated engine coil windings, plugged cooling fins on transformers, capacitors touching broken, heat buildup in cylinder heads of compressors. Any problem is accompanied by a temperature rise, or a temperature curve that is sharply different from the surrounding temperature, so that it can be located with a portable thermal display system. In most cases, problems can be detected and corrected in time before the process is required to be stopped.
Infrared thermometers for the chemical industry
In the petrochemical industry, refineries use temperature display systems as part of routine preventive maintenance programs, including furnace process monitoring and confirmation of thermocouple readings. In the detection of furnace process, 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 of the furnace, which also increases the temperature of the tubes. This high temperature condition will reduce the life of the tube. Because this coking will prevent the product from absorbing the heat of the pipe 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 that in other areas.
