Introduction of the scope of infrared thermometer
- 2018-11-24-

Infrared thermometers can quickly provide temperature measurement when measuring objects. When reading the time of a leaking connection point with a thermocouple, we can read the temperature of almost all connection points with a red infrared thermometer. In addition, due to the solidity of the infrared thermometer, it is light and easy to put in a holster when not in use. The infrared thermometer can be easily carried during factory inspections and daily inspections.

Infrared thermometers can safely read inaccessible or unreachable target temperatures, and can read target temperatures within the range allowed by infrared thermometers. Non-contact temperature measurement can also be performed in unsafe or difficult-to-contact areas. * Measuring is as easy as measuring at hand. Infrared thermometer can measure temperature and humidity from a safe distance. In recent years, it has been widely used in various industries. Infrared thermometer is mainly used in steel, metallurgy and foundry industries.

The infrared thermometer transforms the radiant energy of infrared radiation emitted by an object into an electrical signal. The magnitude of the infrared radiation energy corresponds to the temperature of the object itself. The temperature of the object can be determined according to the size of the converted electrical signal. Today we mainly introduce the scope of application of infrared thermometers, hoping to help users better use infrared thermometers.

I. Steel industry:

The steel industry uses infrared thermometers because the products are in motion and the temperature is very high. A common application in the steel industry is that the temperature is a continuous state where molten steel begins to turn into pieces. Reheating the steel at the same temperature is the key to preventing it from deforming. An infrared thermometer is used to measure the internal temperature of the regenerator. In high-temperature rotary mills, infrared thermometers are used to confirm that the product temperature is within the rotation limits. In cooling mills, infrared thermometers monitor the temperature of the steel as it cools.

2. Plastic industry:

In the plastics industry, infrared thermometers are used to prevent product contamination, to measure dynamic objects, and to measure high-temperature plastics. During the blowing of the blown film, temperature measurement to adjust to heating and cooling can help keep the tension of the plastic intact and its thickness. During the ejection of the cast film, the sensor helps control the temperature to ensure that the thickness of the product is the same. When the sheet is pressed out, the sensor allows the operator to adjust the extinguished heater and cold roll to ensure the quality of the product.

Chemical industry:

In the petrochemical industry, refineries use temperature display systems in routine preventive maintenance procedures. These procedures include monitoring of the furnace process and confirmation of thermocouple indications. In the furnace process inspection, an infrared thermometer is used to detect the proportion of carbon accumulated in the heated surface tube. This agglomeration, known as coking, will lead to a higher firing rate of the furnace and also increase the tube temperature. Such high temperature conditions will reduce the life of the pipe. Because this coking will prevent the product from absorbing the heat of the tube uniformly. When using an infrared thermometer, we find that the tube surface temperature in the junction area is often higher than the tube surface temperature in other areas.
