At present, some of Chinas big city auto emissions is the main source of city air pollution, therefore, the development of clean energy vehicles has become the choice of brook no delay. Compressed natural gas vehicle ( CNG ) with its low energy consumption, pollutant emissions from small and by all countries welcome, is internationally recognized as the most ideal vehicle alternative energy. Development of natural gas vehicle to solve the problems of environment and energy have important significance.

CNG vehicle gas pressure meter ( sensor ) is a very important component of car CNG system, it can directly display the vehicle storage tank and a high-pressure pipeline natural gas pressure, but also can be displayed by the pressure into electric signal output to the cab console on oil gas switch, so as to accurately display the on-board energy storage gas in gas reserves.

Sensing circuit

The product circuit part for Holzer magnetic induction circuit, all electronic components adopt imported elements. The pressure is converted to a voltage signal output, with high accuracy, the consistency of good, long life etc..

( 1) power supply voltage : DC12+2V

( 2) connection mode : Red Black Huang Sangen line. The red line for the power line, black line is a subway line, the yellow line to the voltage signal output line.

( 3) matched switch: indicating lamp type digital display type
