(formerly named   Xi'an Ao Xin Automation Instrument Pneumatic Co.,ltd.) is a leading Chinese company specializing in the Dwyer flowmeter    Pressure Measurement  and some other kinds of products . We are a key member China of Pneumatic Association, and is awarded AAA Credit Grade by Bank of China.
High quality of the raw materials, the precision of the parts, the hard tests during and at the end of production are a warranty of reliability and features. Our real strength is to develop customised products to solve any requirement of utilisation. The production runs conforming to the rigorous ISO 9001/2000 requirements .The product range consists of  pressure switch pressure gauge differential pressure switch  transmitter sensor flowmrter  etc   ,which are found in a variety of industrial applications such as machinery, metallurgy, food, textile and waste treatment.

possessing a digital display gage, control relay switches, and a transmitter with current
output. Combining these three features allows the reduction of several instruments with oneproduct, saving inventory, installation time and money. The Digihelic® Controller is theideal instrument for pressure, velocity and flow applications, achieving a 0.5% full scaleaccuracy on ranges from 5 to 100 in w.c.

The Digihelic® Controller allows the selection of pressure, velocity or volumetric flow
operation in several commonly used engineering units. Two SPDT control relays with
adjustable deadbands are provided along with a scalable 4-20 mA process output. The Series
DH provides extreme flexibility in power usage by allowing 120/220 VAC and also 24 VDCpower which is often used in control panels.

With all this packed into one product it is easy to see why the Digihelic® Controller is theonly instrument you will need for all your pressure applications.
