Where are the main areas of infrared thermometers used?
Infrared thermometers have proven to be an effective tool for detecting and diagnosing faults in electronic equipment. With infrared thermometers, you can continuously diagnose electronic connection problems and detect the functional status of an uninterruptible power supply (UPS) by locating hot spots in the output filter connections on DC batteries, you can check battery components and power distribution panel terminals, switch gear or fuse connections to prevent energy consumption; since loose connectors and combinations generate heat, infrared thermometers help to Identify insulation faults in circuit breakers. Or monitor electronic compressors; daily scanning of transformers for hot spots can detect cracked windings and terminals.
Three of Raytek's non-contact temperature measurement techniques are listed below.
Spot Measurement: Determines the temperature of the entire surface of an object, such as an engine or other piece of equipment.
Differential Temperature Measurement: Comparing the measured temperatures of two independent points, such as a connector or circuit breaker.
Scanning measurement: Detects changes in the target over a wide area or a continuous area. Like refrigeration lines or power distribution rooms.
Key considerations when choosing an infrared thermometer
Temperature range: the product temperature range of -500 ~ 3000 degrees (segments), each model of the thermometer has its own specific temperature measurement range. The temperature range of the selected instrument should match the temperature range of the specific application.
Target size: temperature measurement, the target should be larger than the field of view of the pyrometer, otherwise the measurement error. It is recommended that the size of the measured target exceeds 50% of the field of view of the pyrometer.
Optical resolution (D:S): that is, the pyrometer probe to the target diameter ratio. If the pyrometer is far from the target, and the target is small, you should choose a high-resolution pyrometer.
Measurement of temperature techniques
When measuring the surface temperature of luminous objects, such as aluminium and stainless steel, the reflection of the surface will affect the infrared thermometer readings. Before reading the temperature, you can put a strip of tape on the metal surface, temperature equilibrium, measure the temperature of the tape area.
For an infrared thermometer to be able to move back and forth from the kitchen to the refrigerated area and still provide ** temperature measurements, it is necessary to take measurements after a period of time in the new environment to achieve temperature equilibrium. *It is a good idea to keep the pyrometer in a location where it will be used frequently.
Use an infrared thermometer to read the internal temperature of a fluid food, such as a soup or sauce, which must be stirred, and then the surface temperature can be measured. Keep the pyrometer away from steam to avoid contamination of the lens, which could result in incorrect readings.
