In order to expand the use of a variety of general-purpose pressure controllers, can be applied to the measurement of strong corrosion, high temperature, high viscosity, easy to crystallize, easy to coagulate and solid float media pressure, as well as some of the measurement medium can not be directly into the general-purpose instrumentation and to facilitate the cleaning of the occasions to prevent the build-up of precipitate material pressure detection, must be used by the diaphragm isolator and general-purpose pressure instrumentation to form a system of diaphragm table. Diaphragm gauges are mainly used in petroleum, chemical, pharmaceutical, food, textile and other industrial sectors in the production process of pressure detection. Protection class of this instrument: IP64
