CNG pressure gauge
Our company specializes in 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

reliability. Specification: 1.pressure gauge Case

size:50mm,54mm,63mm,75mm Connection type:bottom connection,back

connection Case material:ABS(balck),alloy

aluminium(LY-12CZ),stainless steel Bezel(lens) material:Acrylic

Tube material:Qsn6.5-0.1 or SUS316L Socket material:HPb59-1 or

SUS316 Connection:G1/4(PF1/4),M14*1.5,ZG1/4(PT1/4),NPT1/4,and

so on. Range:0~400bar/6000psi Accuracy:DIN 2.5% accuracy

2.Sensor circuit the circuit of the product is Hall effect

magnetic induction,all electic parts of an apparatus is

improted from oversea,so the presion and reliablility excal to

other congeneric products.they can change pressure to voltage

signal to output,so this product has many advantages,such

as:high precision and consistency,longevity,and so on. (1)power

supply voltage:DC12+2V (2)connection:red,black and yellow wire

(3)transition switch:indicator light,digital this product is

patent product,PATENT NO.:200520078879.8 The sensing circuitry

utilizes a Hall effect magnetic induction. The superior design

and manufacturing technologies have provided the product with

higher precision and stability, when compared with other

products in the same category. Our product has successfully

opened the market in 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.
