Overview and features of online infrared thermometers
Online infrared thermometers are widely used in many industries. Here are a few examples:
In the glass industry, it is heated to very high temperatures. Infrared thermometers are used to monitor the temperature in furnaces. Handheld 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 the temperature at each processing stage. The wrong temperature or too rapid a temperature change can cause uneven expansion or contraction. For bottle and container products, the molten glass flows to a forehearth that is kept at the same temperature. Infrared thermometers are used to detect the temperature of the forehearth glass. So it should be in the appropriate state at the exit point. In fiberglass products, infrared sensors are used in processing furnaces 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 glass products.
In the plastics industry, infrared thermometers are used to avoid product contamination, measure dynamic objects and measure high-temperature plastics. As the blown film is ejected, temperature measurements to adjust for heating and cooling can help maintain the integrity of the plastic's tension and its thickness. During the ejection process of the thrown film, the sensor helps control the temperature to ensure the thickness and uniformity of the product. As the sheet is being extruded, sensors allow the operator to adjust the extinguishing of the heater and cold roll to maintain product quality.
Additionally, 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 furnace process inspection, infrared monitors are used to detect the proportion of carbon accumulated in the heating surface tubes. This build-up, known as coking, results in higher firing rates in the furnace and also increases tube temperatures. This high temperature condition will reduce the life of the tube. Because this coking will prevent the product from absorbing the heat of the tube evenly. When using an infrared thermometer, we will find that the surface temperature of the pipe in the intersection area is often higher than the surface temperature of the pipe in other areas.
Online infrared thermometer characteristics
1. Small size, light weight, portable, handheld snake-shaped probe, increased flexibility in connection.
2. Wide measuring range: The instrument can detect the leakage amount of SF6 within the leakage rate range of the SF6 switch device, and can be switched between two levels.
3. High accuracy: The instrument is calibrated using advanced calibration methods to provide a highly accurate calibration line, which improves the credibility of SF6 leak detection results and the accuracy of quantitative leak detection.
4. Intuitive display, sound off alarm: It adopts digital LCD with display, which has a simple and intuitive effect. When SF6 is present, the instrument will sound an alarm.
5. Fast response: short recovery time.
