Advantages of Fixed Infrared Thermometers
1. Infrared thermometers are used in the steel 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 warping, and infrared thermometers are used to measure the internal temperature of the regenerator. In high temperature rotary mills, infrared thermometers are used to confirm that the temperature of the product is within rotation limits. In cooling mills, infrared thermometers monitor the temperature of the steel as it cools.
Second, infrared thermometer in the glass industry
In the glass industry, it is 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.
3. Infrared thermometers are used in 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.
4. Infrared thermometer chemical industry
In the petrochemical industry, refineries employ temperature display systems as part of routine preventive maintenance programs. These procedures include monitoring of the furnace process and verification 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.
Five, infrared thermometer can also play a preventive maintenance
With a portable thermal display system, maintenance personnel can identify potential or existing problems. Examples: Overheated engine coil windings, plugged cooling fins on transformers, bad capacitor connections, heat buildup in compressor cylinder head. 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.
