Background
The LNG is liquefied natural gas, and is a clean energy source internationally recognized at present due to its characteristics of being colorless, odorless, nontoxic and noncorrosive, and free from environmental pollution caused by combustion and discharge, and its volume is about 1/600 of the volume of the same amount of gaseous natural gas, and the weight of the LNG is only about 45% of the same volume of water. Besides being widely applied to industry, urban residents and families, the automobile energy-saving gasoline can also be used as automobile energy to replace gasoline and diesel oil. In order to measure the liquid level of the LNG cylinder, a capacitive liquid level sensor is required to be installed on the LNG cylinder.
At present, under the low temperature condition, insulating cover in the capacitive level sensor casing can be because low temperature influences atrophy, and form the space between the inner tube, and the inner tube is rotatory in the transportation to drive the lead wire and just reverse, lead to the lead wire to damage.
