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 is measured in a solid high pressure housing by a free floating precision piston. The piston carries a magnet that is magnetically coupled 

The differential pressure gauge principle is based on measuring the difference between two pressures. As its name suggests, the differential pressure 

Jun 28,  · Manometer vs Pressure Gauge: Key Differences. Pressure measurement is the measure of the force applied by a gas or liquid on a surface. Pressure measurement is an essential measurement in continuous process industries. Usually, manometers and pressure gauges are used for the measurement of pressure. Many technicians usually get confused

1127 Differential Pressure Gauge. The Ashcroft ® 1127 gauges offer a solution for measuring high differential pressures for applications requiring stainless steel wetted materials and aluminum case. Configure Part Number View Datasheet.

Differential pressure is measured using a variety of gauges including: *Magnehelic ® Gauges, *Photohelic ® Gauges, or digital electronic pressure drop indicators. These gauges typically measure differential pressure in units of inches of water gauge (“w.g.) though other scales such as mm of water, mm of mercury, or pascals are used.

The Ashcroft® 1130 gauge is a very economical means for measuring differential pressure in applications where media migration may be acceptable such as 

May 12,  · Differential pressure gauge shows the difference in pressure between two given points, often expressed as DP or ΔP; it is an essential pressure reading found in almost all

Differential pressure is essentially the difference in pressure between two given points. It is a type of pressure measured within different industries using differential pressure sensors.

Designed to measure the difference in pressure between two points in a system and present the resultant differential pressure directly on a single gauge dial A magnetic movement allows the simultaneous sensing of both pressures while completely isolating the gauge function from the pressure chamber without the use of mechanical seals
