The YN series instruments feature excellent seismic resistance and are particularly well-suited for applications involving intense mechanical vibrations and significant pressure pulsations in media that are non-explosive, do not crystallize or solidify, and are non-corrosive to copper and copper alloys—whether the medium is a liquid, gas, or steam. These instruments provide stable indications and clear readings.
They are widely used in sectors such as heavy machinery, mining, petroleum, chemical engineering, metallurgy, and power generation.
Based on the structural principles of the Y-series general pressure gauges, this instrument incorporates internal damping fluid (silicone oil or glycerin), damping tubes, damping plates, and damping screws to mitigate the impact damage caused by intense medium pulsations and environmental vibrations. This ensures measurement accuracy and extends the service life of the instrument.

Working Principle
The instrument relies on internal filling of damping fluid (such as silicone oil or glycerin), assembly of damping tubes, damping discs, and damping screws, based on the structural principle of the Y series pressure gauge. These measures overcome the impact damage caused by severe pulsations of the medium and environmental vibrations to the pressure gauge, ensuring measurement accuracy and prolonging the instrument's service life.
