DIFFERENTIAL PRESSURE MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a differential pressure measuring device capable of easily improving corrosion resistance. SOLUTION: This differential pressure measuring device equipped with a base block and a wet diaphragm installed on one surface of the base block is characterized by being equipped with a plate-like protective plate having one surface provided in contact with one face of the base block and the outside surface of the wet diaphragm, and the other surface in contact with measuring fluid, and comprising corrosion resistant metal material.
