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.

Digital differential pressure gauge is all-electronic structure, battery power supply, easy installation on site. The front end adopts high precision. Piezoresistive differential pressure core is processed by amplifier and microprocessor, and the actual pressure value is displayed by LCD.

The intelligent digital thermometer is flexible in use, simple in operation, easy in debugging and safe and reliable. Be widely used in. Hydroelectricity, tap water, petroleum, chemical, mechanical, hydraulic and other industries, the pressure of the fluid medium to be measured obviously.
