Tips: Working Principle of the Diaphragm Pressure Gauge

The operating principle of the diaphragm cupsule pressure gauge is based on the fundamental physics of elastic deformation. At the heart of the instrument lies a sensitive, flexible diaphragm, which serves as the primary pressure-receiving element.

When the system's medium (such as a liquid or gas) applies pressure, it acts directly on this diaphragm. In response, the diaphragm undergoes a precise, proportional elastic deformation. This mechanical movement is then transmitted through an internal linkage mechanism which efficiently converts the linear displacement of the diaphragm into a rotational motion.

This rotation drives the pointer, which moves across the calibrated scale to provide a clear and direct pressure reading. To guarantee long-term reliability and accuracy, the critical elastic element (diaphragm) is subjected to a series of rigorous quality tests. These include leak tests to ensure integrity, overpressure tests to verify structural safety, and aging tests to confirm performance stability over time, ensuring the diaphragm pressure test gauge performs consistently under varying and demanding conditions.
