WY-X Pressure Gauge are high quality dry pressure gauge designed to provide reliable service on various applications which are mostly in manufacturing or processing industrial, especially for pneumatic process, fabrication, compressed gas and common industrial application.. This series are widely used in gas or liquid tube and vessels, measuring the working pressure of medium such as liquid and gas without danger of explosion, without crystallizing, without freezing and without corrosive function to alloy. It is featured with small volume, ingenious structure, stable performance, safety and reliability and clear display.
The inside mechanical system is made up of junction and spring tube. Because the change of measured pressure effect the movement to free ends of spring tube, drives needle on turnable gear circling by the connection rod, then the dial will display the corresponding pressure value. In order to avoid the movement because of the clearance between the turnable gears, we fix a hairspring on the gears.
