Product brief introduction: differential pressure instrument with double bellows structure, namely the two corrugated pipe are respectively arranged on both sides of the bracket" work" type symmetrical positions. " Work" type bracket of the upper and lower ends are respectively for the movable end and a fixed end, the spring piece is connected between two corrugated pipe; a parallel state, were treated with catheter and the case of high and low voltage connected with a joint; the gear transmission mechanism is directly installed on the bracket of fixed end, and through the pull rod and support activities. Connection; disk is directly fixed on the gear transmission mechanism.

The meter work principle: Based on the pressure sensing element using the two have the same stiffness of corrugated pipe, so at the same measured medium cause the same concentration respectively acts on the movable support, since the spring sheet on both sides of the torque does not produce immunity, the stent is still in the original position, so the gear drive system will not act, the pointer will point zero.

When applying different pressures ( general high end is higher than the low end ), two bellows acting on the movable bracket is not equal to force, which respectively produce a corresponding displacement, and drives the gear transmission mechanism transmission and amplification, the pointer deflection indicator between the differential pressure value.
