Original CNG/LPG high pressure sensor for automotive engines

Product description

CNG/LPG high pressure sensors are alarms that monitor flammable gas leaks. They are widely used in coal mines and factories, and are beginning to be popularized in homes. Used to monitor gas, liquefied petroleum gas, carbon monoxide leakage, prevent gas leakage caused by explosion and incomplete combustion caused by poisoning. The core part of these alarms is the gas sensor, which is a kind of gas sensor. From the perspective of action mechanism, CNG/LPG high-pressure sensors are mainly divided into two types: semiconductor gas sensor and contact combustion sensor. The semiconductor gas sensor is mainly composed of N-type oxide semiconductors such as SnO2, supplemented by precious metals such as platinum or palladium. The reaction of the combustible gas on its surface causes a change in the electrical conductivity of SnO2, thus sensing the presence of the combustible gas. This reaction needs to occur at a certain temperature, so the Pressure Sensor is also heated with a resistance wire. Contact combustion sensor refers to combustible gas and catalyst contact combustion, so that the resistance of platinum coil changes, sensing the presence of gas. The sensor consists of a platinum coil coated with porous alumina containing a precious metal catalyst such as platinum or palladium.
