Wide application and selection of thermometers
Application fields of infrared thermometer
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 Scanning transformers for hot spots detects cracked windings and terminals.
How to measure temperature with an infrared thermometer
Point measurement: measure the temperature of the entire surface of an object, such as an engine or other equipment
Differential temperature measurement: compare the measured temperature of two independent points, like a connector or a circuit breaker
Sweeping Measurements: Detect target changes over wide or continuous areas. Like refrigeration lines or switch rooms.
The main considerations for choosing an infrared thermometer
-Temperature range: The temperature range of Fluke and Optris products is -500 to 3000 degrees (segmented), and each type of thermometer has its specific temperature range. The temperature range of the chosen instrument should match that of the specific application.
-Target size: When measuring temperature, the target to be measured should be larger than the field of view of the thermometer, otherwise there will be errors in the measurement. It is recommended that the measured target size exceed 50% of the pyrometer's field of view.
- Optical resolution (D:S): the ratio of the pyrometer probe to the target diameter. If the thermometer is far away from the target and the target is small, a high-resolution thermometer should be selected.
Measuring Temperature Tips
- When measuring the surface temperature of luminous 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 strip on the metal surface, and measure the temperature of the strip area after the temperature is balanced.
- In order for the infrared thermometer to walk back and forth from the kitchen to the refrigerated area and still provide accurate temperature measurement, 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 frequently used place.
- Use infrared thermometers to read the internal temperature of fluid foods, like soup or sauce, that must be stirred and then the surface temperature can be measured. Keep the thermometer away from steam to avoid contaminating the lens and causing incorrect readings.
