Using Liquid Filled Hydraulic Pressure Gauges

Have you ever seen a pressure gauge that is “broken” because the needle moves wildly over a good portion of the range?

Have you ever seen a good quality gauge fail prematurely? If you have, you have seen applications that would have benefited from liquid filled pressure gauge.

Significant money, in terms of down time, wasted labor, and wasted money at purchase occurs by not properly understanding and implementing the right pressure gauge for an application. In applications with vibration, the needle on the dial, can move, often times wildly, and based on the vibration, not a fluctuation of pressure. The liquid fill material dampens this movement for a clear and accurate reading. No more guessing at the pressure because the needle is moving between 250 and 750 PSI!

The reduced movement will also lead to longer gauge life. Like all moving parts, they will wear sooner or later. The linkages inside your pressure gauge are no different. If they are moving excessively, you will have premature wear and potentially failure of the gauge.

There are also issues of what to fill the gauge with. For best results the fill fluid should be: Clear, somewhat viscous, and inert. The most common fill is glycerin, which meets all of these requirements. However, some applications will call for other fill fluids for various reasons such as: High Temperature, Low Temperature, and Food Grade Issues. It is generally assumed that if a fill fluid is not specified, it is glycerin. If you need another fluid, like vegetable oil or silicon, ask your vendor. In large quantities there should not be much difference in cost.

Properly using liquid fill will make the gauge more useful and give it a longer life. So, when selecting gauges in an application with vibration, use a liquid fill. Since it is the fill material that provides, the stability of the needle and the lessening of wear on the gauge, it is prudent to maximize you purchasing power when buying these gauges. Search the internet for “liquid filled pressure gauges” or “hydraulic pressure gauges” or “hydraulic liquid filled gauges”. When you do this you will find companies that can support your needs at really good prices. Knowing your application and proper searching will increase the lifetime and usefulness of your gauges, not to mention save you some money.
