What are the top 7 applications for infrared thermometers?
Professional nursing technicians are discovering that when temperature is a clear indication of performance or critical condition, Fluke contact thermometers help them find and solve problems faster and more efficiently. Fluke infrared thermometers are fast, portable, accurate, and easy to use: simply point, snap, and read the temperature of the target being measured.
Here are three basic applications where infrared thermometers can help users troubleshoot:
1. Point measurement, to determine the "absolute" temperature of the surface of the object to be measured.
2. Differential temperature measurements, comparing temperatures at two or more locations or at different times.
3. Temperature scanning, to determine the parameters that can indicate the state of failure, such as the temperature of the phase, hot or cold spots, temperature change.
Tip: Ordinary infrared thermometers cannot measure temperature through glass; their readings are the surface temperature of the glass.
For polished metal and reflective surfaces, it may be difficult to measure accurately. If possible, you can use fast-drying paint on the surface of the object to be measured; for high-temperature object to be measured, you can use a hot "engine ceramic reading", you can also use ordinary tape, or the use of spray lubricants (such as WD40) to spray the surface. All of these surface treatment techniques enhance the surface to be measured and allow accurate readings to be obtained.
Industrial installations
Because infrared thermometers use non-contact measurements, there is an increased margin of safety when taking measurements in hazardous areas. With Fluke's non-contact infrared thermometers, it is easy to obtain instantaneous temperatures on the following objects: very hot surfaces, hard-to-reach locations, energized switchboards and equipment, as well as inside and around mobile equipment and machinery.
1. Electrical maintenance, check for heat buildup due to loose connections, set diagnostics for battery pack and switchboard terminals, ballasts, switchgear and fuse connection failures; identify hot spots in output filters on DC battery lines.
2. equipment maintenance, measure the rotating parts and housing inside the motor and gearbox to check for hot spots. Changes in temperature can indicate the development of faults in a wide range of equipment from boxes to reefers. Regularly checking the temperature of the generator and its bearings can effectively prevent costly repairs from occurring.
3. Electric motors, elevated motor temperatures can be a sign of overload, winding damage bearing failure or voltage imbalance. Fokker thermometers can be used to check the operating temperatures of motors, generators and bearings at regular intervals without stopping the equipment. Measurement results from new equipment and equipment in good working order can be archived and used as a measurement reference. By comparing future measurements with the baseline data, performance faults can be recognized very easily.
4. Circuit breakers, with non-contact temperature scanning, can identify overloaded circuits or poor connections. The user can scan the switchgear well for temperature readings, circuit breaker by circuit breaker, wearing appropriate protective equipment. If a circuit breaker has a high temperature, it indicates a possible fault. A further detailed check can then be made using a Fluke-type meter.
5. Air conditioning HVAC systems, easily and efficiently diagnose boiler and circulation failures, cooling and chilling systems, heat exchangers, ducts and distribution systems. Scan compressors and condensers for overheating or blocked ducts.
6. Steam systems, with a Fluke non-contact pyrometer can read the surface temperature of condensate valves to determine if the door has failed to open or close. When measuring from input to output, a significant drop in temperature should occur. If no drop in temperature occurs, the valve is not open; however, if the drop is too great, the inter door is fully closed. By monitoring the valve, you can more easily determine the fault.
7 . Insulation test, measure the insulation of the pipes and boiler to check for hot spots. Scan with a Fluke infrared thermometer and check the maximum temperature reading after completing the scan, which can be up to 204°C and higher in non-insulated areas.
