Differential pressure gauges are some of the most underutilized and misunderstood products in manufacturing. As a result of a near complete lack of mention from engineering eduction, we see engineers constantly using two standard pressure gauges, when they could just use one differential pressure gauge. From applications involving filtration system, measuring flow rates using the Bernoulli Principle, displaying liquid levels in cryogenic tanks, detecting leaks in systems, and so much more, these capable instruments should be part of every engineer’s toolbox.
Simply put, a differential pressure gauge measures the difference in pressure between two connections. Let’s imagine an application where you have a tank at 100 psi and another at 95 psi. If you connect a differential pressure gauge between those two tanks, you will read 5 psi. There are a few different gauge designs to achieve this. Differential Pressure Plus utilizes a design known as a “Magnetic Coupling.” Each gauge has a magnetic piston that moves back and forth like a sea-saw depending on the differential pressure. As a result, the linear movement of this magnetic piston pushes and pulls on a rotary magnet that connects to the pointer. This “magnetic rack and pinion” provide the readout.
From custom dial printing, logos, specialty connections, and more, Differential Pressure Plus can customize to your needs. We’ve built portable testing kits, supplied gauges with fittings pre-installed, and have built custom install kits a a wide variety of applications.
