Our company designing and manufacturing CNG Automobile Combustion Gas Pressure Gauge (Sensors). The product is compatible with various types of commercially available adaptors and switchers, such as LOGAS, LOVATO, BIGAS, etc.

The product includes two major parts:
The pressure gauge and the sensor circuitry. One of the key parts of the pressure gauge, the tube, is made with a high frequency welding machine using Ag45CuQsnCr. The seal performance of each gauge has been evaluated through a leak test under 550-600bar for at least 30 minutes. The working pressure from CNG automobile combustion system is usually lower than 200bar. As a result, each gauge has a fairly security and eliability.
Application
The corresponding pressure gauge is aimed to be used for the measurement of the tank capacity for CNG-Cars. Scale Ranges up to 0...400 Bar
Our product has successfully opened the market in Australia, France, India, Iran, Thailand, Italy, and other countries and regions. We would like to do our best to offer our customers with the products of high quality and low cost.
