The instrument adopts a double corrugated pipe structure, that is, two corrugated pipes are respectively installed on the symmetrical positions on both sides of the "I" shaped support. The upper and lower ends of the I-shaped frame are respectively a movable end and a fixed end, and the middle is connected by a spring sheet; The two bellows are connected with the low pressure connector on the case, and the gear transmission structure is directly installed on the fixed end of the bracket. And is connected with the movable end of the bracket through a pull rod; The dial is directly fixed on the gear transmission mechanism.

When different pressures are applied (generally, the high pressure end is higher than the low pressure end), the forces acting on the movable support by the two bellows are not equal, so that the displacement is generated separately, and the gear transmission mechanism is driven and amplified. The differential pressure value indicated after the pointer is deflected.
