YN63 Liquid Filled Pressure Gauge 0-400 Bar 0-6000 PSI Dual Scale Bottom Mount

Product Overview

The liquid-filled construction effectively dampens pointer vibration caused by pressure pulsation, mechanical shock, and equipment vibration, providing stable readings and extending the service life of the gauge. The 0-400 Bar (0-6000 PSI) pressure range makes it suitable for medium and high-pressure hydraulic applications. Similar 63mm bottom-entry glycerin-filled gauges are commonly used in hydraulic systems and provide dual PSI/Bar scales for industrial pressure monitoring. 

Technical Specifications

Working Principle

The gauge operates using a Bourdon tube sensing element. As system pressure enters through the bottom connection, the curved Bourdon tube deforms proportionally to the applied pressure.

This movement is transferred through a precision gear mechanism that drives the pointer across the dial face, providing a direct pressure indication.
