DIFFERENTIAL PRESSURE PRODUCTS SELECTION GUIDE

Differential Pressure Gauges, Switches and Transmitters

Orange Research differential pressure gauges are 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 patented 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. >> More about our differential pressure gauges, switches & transmitters

Piston vs. Diaphragm

Our piston sensor models are primarily designed for liquid applications. They exhibit a slight amount of bypass as the fluid migrates from the high to the low pressure port. Because gas molecules are smaller, the migration is often deemed too great for the application. We incorporate a flexible Teflon cup seal in our sensor, which keeps the bypass very low.

In our diaphragm sensor models the high and low-pressure ports are completely isolated from each other. There is no bypass and therefore they are appropriate for air or gas along with liquids. They also come in a variety of sizes allowing for very sensitive measurements. Consider some of our diaphragm models for the addition of a diaphragm seal. Consult our factory for details.
