What is a differential pressure gauge?

In short, the differential table measuring the pressure differential between the two connection. Let us suppose, therefore, an application, your tank pressure of 100 pounds per square inch, another pressure of 95 pounds per square inch. If the connection between the two tanks differential pressure table, is reading to 5 psi.

There are some different pressure gauge design can achieve this goal, but the differential pressure increases the manufacturer called “magnetic coupler” design. Each gauge has a magnetic piston that moves back and forth like a sea saw, depending on the pressure difference. As a result, the magnetic linear motion of the piston to push and pull the rotating magnet that is connected to the pointer. This “magnetic rack and pinion” provides readings.
