50mm Linear Electrical Output Signal CNG Pressure Gauge 400 bar Vehicles Fuel Tanks
Description
At present, auto emissions are the main source of city air pollution. The development of clean energy vehicles has become more and more important. Compressed natural gas vehicle (CNG ) with low energy consumption, pollutant emissions is internationally recognized as the most ideal vehicle alternative energy. Development of natural gas vehicle to solve the problems of environment pollution and energy saving is significantly important.
Applications
Measurement of the filling pressure in gas tanks for CNG vehicles
