Technology and Method of Using Infrared Thermometer to Measure Temperature
Infrared thermometers provide quick temperature measurements, and in the time it takes to read one leaky junction with a thermocouple, nearly all junctions can be read with an infrared thermometer. Also because the infrared thermometers are solid, lightweight (all under 10 ounces), and easy to carry in a holster when not in use. So you can carry it when you are doing factory inspections and daily inspections.
Another advanced feature of infrared thermometers is accuracy, usually within 1 degree. This capability is especially important when you are doing preventive maintenance, such as monitoring severe production conditions and special events that will cause equipment damage or downtime. Because most equipment and plants run 365 days, downtime equates to lost revenue. Prevent such losses by scanning all on-site electrical equipment—circuit breakers, transformers, fuses, switches, buses, and switchboards—for hot spots. With an infrared thermometer, you can quickly detect even small changes in operating temperature, allowing problems to be fixed in the bud, reducing the expense and scope of repairs due to equipment failure.
Safety is the most important benefit of using an infrared thermometer. Unlike contact thermometers, infrared thermometers can safely read inaccessible or inaccessible target temperatures, and you can read the target temperature within the range allowed by the instrument. Non-contact temperature measurement can also be performed in unsafe or difficult-to-contact temperature areas, such as near steam valves or heating furnaces, where they do not need to risk burning their fingers when inadvertently contacting the temperature measurement. Accurate measurement of supply/return air temperatures up to 25 feet overhead is as easy as having it at hand. Infrared thermometers all have laser aiming for easy identification of the target area. With it your work becomes much easier.
The following are three techniques for measuring temperature with non-contact thermometers:
Sweeping Measurements: Detect target changes over wide or continuous areas. Like refrigeration lines or switch rooms.
Differential temperature measurement: Compare the measured temperature of two independent points, like a connector or a circuit breaker.
Point measurement: Determining the temperature of the entire surface of an object, like an engine or other equipment.
Accurate temperature measurement method:
Use infrared thermometers to read the internal temperature of fluid foods, like soups or sauces, that must be stirred before the surface temperature can be measured. Keep the thermometer away from steam to avoid contaminating the lens and causing incorrect readings.
In order for the infrared thermometer to walk back and forth from the kitchen to the refrigerator and still provide accurate temperature measurements, it must be measured after a period of time in the new environment to achieve temperature equilibrium. It is best to place the thermometer in a place that is frequently used.
When measuring the temperature of the surface of shiny objects, such as aluminum and stainless steel, the reflection of the surface will affect the reading of the infrared thermometer. Before reading the temperature, put a rubber strip on the metal surface, and measure the temperature of the strip area after the temperature is balanced.
The main application fields of infrared thermometers:
Infrared thermometers have proven to be effective tools for detecting and diagnosing faults in electronic equipment. Can save a lot of money, with infrared thermometers, you can continuously diagnose electrical connection problems and by looking for hot spots at the output filter connection on the DC battery, to detect the functional status of the uninterruptible power supply (UPS), you can test the battery Components and power distribution panel terminal blocks, switch gears or fuse connections to prevent energy loss; as loose connectors and combinations can generate heat, infrared thermometers help identify insulation faults in circuit breakers or monitor electronic compressors; daily scans Transformer hot spots detect cracked windings and terminals.
