Infrared temperature measurement (thermometer) detection principle
Industrial general medical thermometry is used in areas where infectious diseases occur. It uses far-infrared rays to emit light signals to measure the temperature of the human body without touching the human body. It has special uses during the SARS period, bird flu period, etc. The temperature is designed to be -50~480℃, and low temperature measurement of minus 50 degrees can be easily achieved, and it can also be used normally in areas with low temperatures such as the northeast and northwest.
What is the principle of the temperature measuring gun?
1. The principle of the temperature measuring gun is: the infrared temperature measuring gun is composed of optical system, photoelectric detector, signal amplifier, signal processing, display output and other parts.
2. The optical system collects the target infrared radiation energy of its field of view. The size of the field of view is determined by the optical components and their position of the thermometer. When using an infrared radiation thermometer to measure the temperature of an object, the amount of infrared radiation of the object in its band range must first be measured, and then the temperature of the object being measured is calculated by the thermometer.
use
1. Human body temperature measurement: Accurately measure human body temperature, replacing the traditional mercury thermometer.
2. Skin temperature measurement: Measuring the surface temperature of human skin, such as medical skin surface temperature measurement.
3. Object temperature measurement: Measure the surface temperature of an object, for example, it can be used to measure the temperature of the surface of a tea cup.
4. Liquid temperature measurement: Measure the temperature of liquids, such as the temperature of baby bath water, the temperature of milk in the bottle, etc.
Thermometer gun (thermometer)
Mainly used for rapid temperature measurement in metallurgy and foundry industries. It connects micro thermocouples, temperature measuring guns, compensation wires, and secondary instruments to form a temperature measurement loop and transmit temperature signals. Features: The positive and negative poles of the plug are made of corresponding types of alloy materials, and advanced welding technology is used to eliminate the third component. , to improve the accuracy of temperature measurement. The insulation part is made of polymer materials, which can withstand heat up to 200℃ or above.
