The Skills and Methods of Infrared Thermometer for Accurately Measuring Temperature
The infrared thermometer consists of optical system, photodetector, signal amplifier and signal processing. Display output and other parts. The optical system condenses the infrared radiation energy of the target in its field of view. The infrared energy is focused on the photodetector and converted into a corresponding electrical signal, which is then converted into the temperature value of the measured target.
Infrared thermometers can quickly provide temperature measurement. Within the time of reading a leaking connection point with a thermocouple, the temperature of almost all connection points can be read with an infrared thermometer. In addition, the infrared thermometer is solid. Lightweight. (Both lighter than 10 ounces), and easy to put in a leather case when not in use. So when you are in the factory inspection and daily inspection work, you can carry it.
Another advanced feature of infrared thermometers is accuracy, usually within 1 degree. This performance 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 factories operate for 365 days, downtime is equivalent to reducing revenue. To prevent such losses, scan all on-site Electronic devices-circuit breakers. transformer. fuse. switch. Bus and switchboards to find hot spots. With an infrared thermometer, you can even quickly detect small changes in operating temperature, and you can solve the problem when it is budding, reducing the cost of equipment failure and the scope of maintenance.
Safety is the most important benefit of using infrared thermometers. Unlike contact thermometers, infrared thermometers can safely read the temperature of inaccessible or inaccessible targets, and you can read the target temperature within the allowable range of the instrument. Non-contact temperature measurement can also be carried out in areas that are unsafe or difficult to contact temperature measurement, such as near steam valves or heating furnaces. They do not need to run the risk of inadvertently burning fingers when contacting temperature measurement. Accurate measurement of the supply/return air temperature of 25 feet above the head is as easy as measuring at hand. Raytek infrared thermometers have laser aiming, which is easy to identify the target area. With it, your work becomes much easier.
Infrared thermometers have been proven to be effective tools for detecting and diagnosing faults in electronic equipment. You can save a lot of money. With an infrared thermometer, you can continuously diagnose electronic connection problems and detect the function status of the uninterruptible power supply (UPS) by finding the hot spot at the output filter connection on the DC battery. You can check the battery The components are connected to the power distribution board terminal, switch gear or fuse to prevent energy consumption; since loose connectors and combinations will generate heat, infrared thermometers can help identify the insulation failure of the circuit interrupter. Or monitor electronic compressors; daily scanning of transformer hot spots can detect cracked windings and terminals.
The three temperature measurement technologies of Raytek non-contact thermometers: 1. Point measurement: measure the temperature of the entire surface of an object, like an engine or other equipment; 2. Temperature difference measurement: compare the measured temperature of two independent points, like a connector or a circuit breaker ; 3. Scanning measurement: Detect target changes in a wide area or continuous area. Like refrigeration pipelines or power distribution rooms.
The main considerations when choosing an infrared thermometer: 1. Temperature range: Each type of thermometer has its specific temperature range. The temperature range of the selected instrument should match the temperature range of the specific application. 2. Target size: When measuring temperature, the measured target should be larger than the field of view of the thermometer, otherwise there will be errors in the measurement. It is recommended that the size of the target to be measured exceeds 50% of the field of view of the thermometer. 3. Optical resolution (D:S): the ratio of the diameter of the thermometer probe to the target. If the thermometer is far away from the target and the target is small, a high-resolution thermometer should be selected.
Accurate temperature measurement techniques; when measuring the surface temperature of light-emitting objects, such as aluminum and stainless steel, the reflection of the surface will affect the reading of the infrared thermometer. Before reading the temperature, a rubber strip can be placed on the metal surface. After the temperature is balanced, the temperature of the rubber strip area can be measured. If the infrared thermometer can move back and forth from the kitchen to the refrigerated area and still provide accurate temperature measurement, it is necessary to measure the temperature after a period of time in a new environment to achieve temperature equilibrium. It is best to place the thermometer in a place where it is frequently used.
Use an infrared thermometer to read the internal temperature of liquid food, like soup or sauce, which 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.
