50mm 400 bar Stairstep Signal CNG Pressure Gauge for CNG Cars
Description
CNG vehicle gas pressure meter (or CNG sensor) is a very important component for car CNG system, it can not only 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.
Applications
Measurement of the filling pressure in gas tanks for CNG vehicles
