The SI-D2000 Differential Pressure Gauge (Digital differential pressure gauge)

is an economical means for measuring pressure between two independent pressure sources.

Used on process monitoring or controls,

where small migration of the process media is permissible.

Intended for hydraulic oil, non-corrosive applications,

and some air and gas applications.

SI-D2000 Differential Pressure Gauge working principle

The D2000 series differential pressure gauge is an elastic differential pressure gauge,

that uses a spiral magnetic coupling technique

and uses a rubber diaphragm as a sensitive component.

When differential pressure

(including positive pressure and negative pressure)

acts on two pressure chambers separated by a diaphragm.

The diaphragm is deformed to displace the central portion,

and the leaf spring with the magnetic steel adjustment range is moved to rotate the screw shaft,

by magnetic coupling,

and the pointer rotates with the shaft to indicate the pressure difference on the dial of the meter,


The purpose of measuring differential pressure is achieved.
