purpose

Diaphragm pressure gauge is suitable for measuring the pressure or negative pressure of various flow media with certain corrosion, non coagulation or non crystallization

Structural principle

The instrument consists of a measuring system (including flange joints, corrugated diaphragms), a transmission indicator mechanism (including connecting rods, gear transmission mechanisms, pointers, and dials), and a housing (including a case and cover ring). The instrument housing is a splash proof structure with good sealing, which can protect its internal mechanism from contamination.

The working principle of the instrument is based on the deformation of the elastic element (diaphragm on the measurement system). Under the pressure of the measured medium, the diaphragm is forced to undergo corresponding elastic deformation displacement, which is amplified by the transmission mechanism through the connecting rod group. The measured value is gradually indicated on the dial by the pointer on the fixed gear.
