What is a dangerous liquid detector?

1. Principle of dangerous liquid detector

A technique called quantitative electrical topography is used to measure the spatial distribution of electronic properties of a medium, so that the properties of the liquid can be determined regardless of the material of the container. Air gap is allowed between the equipment and the container. Then, the electronic properties (dielectric constant and conductivity) of the liquid determine whether the liquid is flammable or explosive. The device is completely electronic and does not contain any radioactive or microwave materials or other potentially dangerous components. Principle: determine the permittivity and conductivity of the liquid to be tested, so as to judge its flammability and explosiveness. The detector can distinguish the flammable and explosive liquids such as sulfuric acid, gasoline, acetone and ethanol from the safe liquids such as water, cola, milk and juice without directly contacting with the liquid. When this method is used to detect the liquid, the detection result has nothing to do with the size of the container where the liquid is to be measured, and the air gap between the detector and the container will not affect the measurement result.

2. Types of dangerous liquid detector

The detector can detect a variety of flammable and explosive liquids. Such as: gasoline, diesel oil, kerosene, anhydrous ethanol, acetone, benzene, banana water, ether, dichloromethane, trichloroethylene, petroleum ether, turpentine, liquid paraffin, toluene, xylene, ethyl acetate, n-butanol, dichloroethane, n-pentane, cyclohexane, cyclohexane, carbon disulfide, methanol, isopropanol, ethylenediamine, nitromethane, liquid explosive (IED), etc Flammable and explosive liquid.


3. Application scope of dangerous liquid detector

The instrument can be widely used in safety inspection, terrorist attack prevention, fire prevention and other aspects

Transportation department: railway, station, airport, subway, port, etc

Government departments: Embassy, police station, fire department, court, procuratorate, border station, military, etc.; public places, etc

Large meeting places, stadiums, theaters, shopping malls and other crowded places

4. Use method of dangerous liquid detector

The operation of the hand-held liquid detector is very simple. When using it, just place the probe of the hand-held liquid detector on the side of the container to be tested (glass bottle, iron bottle, plastic bottle, etc.), the detection height is lower than the liquid level in the container, then press the detection button, the green indicator light will be on, and the words "O" and "safe liquid" will appear on the display screen to indicate that the liquid in the container is safe; red means When the indicator light is on, the words "X" and "dangerous liquid" appear on the display screen, and the alarm sound is heard at the same time, indicating that the liquid in the container is flammable and explosive. The liquid detector does not contain ion, microwave radiation source and other potential dangerous elements, which is harmless to operators.

5. Precautions for dangerous liquid detector

1)The radiation of electric appliances, mobile phones, etc. that ordinary people contact is non ionizing radiation. According to the current research, this radiation has no harmful effect on human beings.

2)Use the liquid level detector to comply with the manufacturer's safety specifications, and do not let yourself get additional injury.

3)The radiation dose produced by the liquid level detector must be very small, but don't neglect it.

4)Liquid level detector, because it uses nuclear technology (the vast majority), the radiation produced is nuclear radiation, which is a kind of ionizing radiation. Therefore, in the process of use, it is necessary to observe the safety regulations of the manufacturer, do not let yourself suffer additional injury, and it is recommended to follow the operation rules, or accompanied by relevant personnel.
