Range of application of the infrared thermometer
Measuring electrical equipment
A non-contact infrared thermometer can measure the surface temperature of an object from a safe distance, making it an indispensable tool in electrical equipment maintenance operations.
Application in Electrical Equipment
In the following applications, it can effectively prevent equipment failures and unplanned power outages.
The connector electrical connection area will gradually loosen the connector due to repeated heating (expansion) and cooling (contraction) generating heat, surface dirt, carbon deposition, and corrosion. A non-contact thermometer can quickly determine the temperature rise indicating a serious problem.
Electric motor - To maintain the lifespan of the motor, check if the temperature of the power supply connection wire and circuit breaker (or fuse) is consistent.
Electric motor bearings - check for hot spots and regularly repair or replace them before any problems cause equipment failure.
Motor coil insulation layer - By measuring the temperature of the motor coil insulation layer, its lifespan is extended.
Measurement between phases - Check if the temperature between the wires and connectors of induction motors, large computers, and other equipment is the same.
The winding of the transformer air-cooled device can be directly measured with an infrared thermometer to check for excessive temperature, and any hot spot indicates damage to the transformer winding.
Uninterruptible Power Supply - Determine the hotspot of the connection line on the UPS output filter. A low temperature point indicates that the DC filtering circuit may be open.
Backup Battery - Check the low-voltage battery to ensure proper connection. Poor contact with the battery connector may heat up enough to burn the battery core rod.
Ballast - Check for overheating before the ballast begins to smoke.
Public facilities - identify hotspots for connectors, wire joints, transformers, and other equipment. Some models of optical instruments have a range of 60:1 or even larger, making almost all measurement targets within the measurement range.
