With the continuous development of science and technology , coal mine safety issues have attracted more and more attention. In order to ensure the safety of miners, coal mining companies need to take a series of safety measures. Among them, oxygen content is one of the important factors affecting coal mine safety. Oxygen itself is a non-toxic and harmless gas, but when the oxygen concentration is too high or too low, it will make people feel uncomfortable and cause discomfort to the human body due to lack of oxygen. In order to avoid many industrial environments and prevent workers from experiencing hypoxia before entering the work, it is very necessary to install mining oxygen alarms.
Mining oxygen alarms are mainly used for real-time monitoring of oxygen concentration in confined spaces such as coal mines. When the oxygen concentration is lower or higher than the safe range, the alarm will send out audible and visual alarm signals in time to remind miners to take corresponding measures to prevent oxygen hazards. Safety accidents caused by abnormal concentration. Compared with traditional electrochemical oxygen sensors for monitoring abnormal oxygen concentration , mining optical oxygen sensors have better environmental adaptability. It works based on optical principles and has the advantages of high precision, high reliability and long life, providing important safety guarantees for miners.
British SST fluorescent oxygen sensor (O2 sensor) - LOX-02/LOX-01 usually contains a light source, an optical signal detector and an oxygen sensor. The light source emits a light signal, and after passing through the oxygen sensor, the optical signal detector measures the intensity of the light signal passing through the oxygen sensor. There is a certain relationship between the intensity of this light signal and the oxygen concentration, so the change in oxygen concentration can be determined by measuring the intensity of the light signal. It is not affected by environmental factors such as temperature , humidity and pressure , and can work stably under working conditions.
In addition, the British SST fluorescent oxygen sensor (O2 sensor)-LOX-02/LOX-01 is used to measure the ambient oxygen partial pressure (ppO2). Measure oxygen partial pressure and temperature. The addition of an external air pressure sensor allows the sensor to output oxygen concentration values and air pressure values; combined with the traditional advantages of low power consumption of electrochemical sensors, the non-consumption sensing principle makes it have a longer life. And LuminOx has oxygen pressure and temperature compensation, allowing it to accurately work in a wide environmental range without the need for additional compensation systems. Unlike other sensor technologies, LuminOx is extremely stable and environmentally friendly, does not contain lead or any other toxic materials, and is not affected by cross-interference from other gases.
