Infrared thermometer . . Com / by optical systems, photodetectors, signal amplifiers and signal processing. Display output and other components. The optical system converges the target infrared radiation energy in its field of view. The infrared energy is focused on the photodetector and converted into a corresponding electrical signal. The signal is then converted into the measured target temperature value.
1. The benefits of using infrared thermometers are as follows:
Convenient! The infrared thermometer can quickly provide temperature measurements. With a thermocouple reading a leaky connection point, almost all temperatures can be read with an infrared thermometer. In addition, infrared thermometers are relatively solid and lightweight. (All lighter than 10 ounces), and easy to put in a holster when not in use. So you can carry it when you are on the factory tour and daily inspection work.
Accuracy! Another advantage of infrared thermometers is accuracy. Usually the accuracy is within 1 degree. This performance is especially important when doing preventative maintenance, such as monitoring harsh production conditions and special events that will result in equipment damage or downtime.
Since most plants still have plants operating for 365 days, downtime equates to reduced revenues. It is important to prevent such losses by scanning all on-site electronic equipment - circuit breakers, transformers, fuses, switches. The bus also has power strips to find hot spots. With infrared thermometers, you can even quickly detect small changes in operating temperatures, solve problems when they sprout, and reduce the expense of equipment failure and maintenance.
Safety! Safety is the most important benefit of using an infrared thermometer. Unlike other contact thermometers, infrared thermometers can safely read inaccessible or unreachable target temperatures, and you can read the target temperature within the range allowed by the instrument. Non-contact temperature measurements can also be performed in areas that are unsafe or where contact temperature measurement is difficult. Like steam valves or furnaces, they do not need to inadvertently burn fingers when exposed to temperature measurements. Precise measurements of the temperature of the supply/return port at 25 feet above the head are as easy as measuring at hand.
2. The main area of ​​use is where infrared thermometers have proven to be effective tools for detecting and troubleshooting electronic devices. You can save a lot of money. With the infrared thermometer, you can continuously diagnose the electronic connection problem and find the functional status of the uninterrupted power supply (UPS) by looking for hot spots at the output filter connection on the DC battery. The inspection battery assembly also has power distribution board terminals, switch gears or fuse connections to prevent energy consumption; since the loose connectors and the combination will generate heat, the infrared thermometer will help identify the insulation failure of the circuit breaker. Or monitor the electronic compressor; scan the hot spot of the transformer to detect cracked windings and terminals.
3. How to Measure Temperature with Infrared Thermometer The following are the three temperature measurement techniques for non-contact thermometers:
Point measurement: Measure the total surface temperature of an object, such as the temperature difference measurement of an engine or other device: Compare the measured temperature at two independent points, like the connector or circuit breaker scan measurement: Detect the target change in a wide area or continuous area. Like cooling lines or distribution rooms.
4, choose the main consideration of infrared thermometer temperature range: Each type of thermometer has a specific temperature measurement range. The temperature range of the selected instrument should match the temperature range of the specific application.
Target size: When measuring temperature, the measured target should be larger than the field of view of the thermometer, otherwise the measurement has errors. It is recommended that the size of the target to be measured exceeds 50% of the field of view of the thermometer.
Optical resolution (D:S): is the ratio of probe to target diameter. If the thermometer is far from the target and the target is small, a high-resolution thermometer should be selected.
5, accurate measurement of temperature techniques When measuring the surface temperature of luminous objects, such as aluminum and stainless steel, the reflection of the surface will affect the infrared thermometer readings. Before reading the temperature, a strip can be placed on the metal surface. After the temperature is balanced, the temperature of the strip area is measured.
If you want an infrared thermometer to move around from the kitchen to the cold storage area and provide accurate temperature measurements, measure the temperature balance after a period of time under the new environment. It is best to place the thermometer in a place that is frequently used.
Use an infrared thermometer to read the internal temperature of the fluid food, such as soup or sauce, which must be agitated and then the surface temperature can be measured. Keeping the thermometer away from steam to avoid contamination of the lens can cause incorrect readings.
