CNG Pressure Gauge

Specification Sheet for Pressure Gauge RIGCHINA- Component Code: 070-08 -001 Application The corresponding pressure gauge is aimed to be used for the measurement of the tank capacity for CNG-Cars. Design according to EN 837-1, Scale Ranges up to 0..400 Bar Technical Information Norm: EN 837-1 Nominal size : 50mm, 54mm,63mm,75mm Accuracy class : 2.5 Ingress protection : IP54 Scale range : 0 ... 400 bar/6000psi (or dual scales) Working pressure : Steady: 3/4 x of full scale value Fluctuating: 2/3 x of full scale value Short time: full scale value Bezel : Screw-retained bezel, black with cap Operating temperature : At max. working pressure of 260 bar, -40 ...+125 °C Temperature effect : When temperature of the pressure element deviates from reference temperature (+20 °C): ± max 0,4 %/10 K of the span Pressure connection : Copper alloy, lowerMount, Back Mount NS 50: G 1/4 B, SW 14, M14×1.5, ZG1/4(PT1/4), NPT1/4, and so on. 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.
