Infrared temperature concept

Infrared temperature concept

Infrared temperature usually refers to the surface temperature of an object measured by infrared technology. This measurement takes advantage of the fact that all objects emit infrared radiation, even at room temperature. Infrared thermometers (or infrared thermometers) calculate an object's surface temperature by capturing this infrared radiation and converting it into an electrical signal.

Working principle

Infrared thermometers work based on the relationship between the infrared radiation emitted by an object and its temperature. Specifically, when an object's temperature is above absolute zero, it continuously emits infrared radiation. Infrared thermometers collect this radiation through their optical system and focus it onto the detector. The detector converts the received radiation energy into an electrical signal, which is then processed and calculated through the built-in circuit, and finally shows the temperature of the object.

Application field

Infrared thermometers are used in a wide range of applications, including but not limited to:

Medical: Used for rapid measurement of human body temperature, especially during epidemics such as SARS and bird flu.

Industrial: Used to monitor the temperature of production equipment, help prevent equipment failures and ensure the safety of production processes.

Home: Used to measure the surface temperature of objects in daily life, such as the temperature of the baby's bath water, the milk temperature in the bottle, etc

Matters needing attention

When using infrared thermometers, the following points need to be noted to ensure measurement accuracy:

Avoid steam and dust: Use in environments where there is a lot of steam or dust may cause measurement errors.

Measuring surface temperature: Infrared thermometers can only measure the surface temperature of an object, not the internal temperature.

Calibration and maintenance: Regular calibration and maintenance of infrared thermometers ensures their long-term accuracy and reliability.

In summary, infrared temperature is a kind of object surface temperature measured by infrared technology, which has the advantages of fast, non-contact and safety, and is suitable for a variety of scenarios. However, in order to obtain accurate measurement results, users need to pay attention to the correct method of use and environmental conditions.

Effects of natural gas leakage on the human body

图片
The effects of natural gas leakage on the human body depend on factors such as the amount of leakage, exposure time, and personal physical condition. The specific effects are as follows: Acute health effects Hazard of suffocation The main component of natural gas is methane. If the concentration in the air is too high, it will reduce the oxygen concentration and cause suffocation. When people are in such an environment, the body will experience symptoms such as difficulty breathing and dizziness due to lack of oxygen. In severe cases, it may lead to coma or even death. Irritation Natural gas may contain toxic gases such as hydrogen sulfide, which irritates the human respiratory tract, causing symptoms such as difficulty breathing and coughing. If you are in an environment containing such gases for a long time, the respiratory tract will be continuously irritated and the damage will be aggravated. Explosion and fire risks After natural gas leaks, once it encounters open flames or high t...

The impact of air quality on health

Impact on the Respiratory System Air pollution is particularly harmful to the respiratory system. Particulate matter (such as PM2.5 and PM10) can enter the respiratory tract, irritating the nose and throat, causing symptoms such as coughing, wheezing, and difficulty breathing. Long-term exposure can increase the incidence of chronic obstructive pulmonary disease (COPD), bronchitis, and asthma. Furthermore, pollutants damage the alveoli and respiratory mucosa, reducing lung ventilation and air exchange, decreasing vital capacity, and gradually weakening lung function, affecting the body's breathing capacity and endurance. Impact on the Cardiovascular System Particulate matter and other particles in air pollution can enter the bloodstream, triggering inflammation and oxidative stress, promoting the formation of atherosclerotic plaques, and increasing the risk of cardiovascular diseases such as coronary heart disease, myocardial infarction, and stroke. Pollutants can also affect the ...

The role of chlorine sensors in agricultural automation

In the field of agricultural automation, although chlorine is not as well known as soil nutrients, temperature and humidity, it will have an impact on agricultural production in certain scenarios. Chlorine sensors can also play an important role. The following explains their roles from different aspects:   Ensure agricultural water safety Monitor irrigation water quality In some areas, water disinfected with chlorine may be used for agricultural irrigation. Chlorine sensors can monitor the chlorine content in irrigation water in real time to ensure that it is within a safe range, avoid damage to crops due to excessive chlorine content, and affect crop growth and yield.   Prevent water pollution If the source of agricultural water is polluted by industrial wastewater, it may contain excessive chlorine. Chlorine sensors can detect this abnormality in time and remind farmers to take corresponding measures, such as changing the water source or further treating the water, to ensur...
