The Mercoid DA31-3 stainless steel diaphragm pressure switch is a compact, industrial-grade device that uses a stainless steel diaphragm to translate sensed pressure into an electrical signal, part of Mercoid’s AMETEK family. The diaphragm provides reliable isolation of the sensing element from process media, helping resist corrosion and contamination in low-pressure monitoring applications with an operating range of 8–15 psig. In Mercoid's DA31 family, submodels such as DA31-3-2 and DA31-3-3 illustrate different electrical configurations within the same series, designed for robust performance in industrial environments.
