Pressure element: Copper alloy, Helical type Movement: Copper alloy Dial : NS 50: white aluminium, with pointer stop pin Pointer: Black plastic, special design Case: Black steel Window : Polycarbonate with integrated optoelectronics Electronics Supply voltage: 12 V 40 bar +/- 10 bar = 2.5 V +/-1 V 65 bar +/- 10 bar = 5 V +/-1 V 100 bar +/- 10 bar = 7.5 V +/-1 V 140 bar +/- 10 bar = 11.3 V +/-1 V Supply voltage: 5 V Operating range variable 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 550600bar 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.
