D2000 Differential Pressure Gauge

The D2000 series differential pressure gauges are elastic differential pressure instruments that utilize advanced spiral magnetic coupling technology and employ silicone diaphragms as sensitive elements. When air pressure (positive pressure, negative pressure, or differential pressure) acts on the two pressure chambers separated by the diaphragm, the diaphragm deforms. This deformation pushes the leaf spring equipped with a magnetic steel, causing the magnetically coupled spiral shaft to rotate up and down. Simultaneously, it drives the pointer to indicate the differential pressure reading on the instrument's dial, thereby achieving the purpose of measuring differential pressure.
