Description
The design principle and material selection of the diaphragm pressure gauge allows them to meet the stringent demands occurring in service and industrial processing plants. All wetted parts can be coated with special materials to protect them against aggressive media. As a result of the high actuating forces, diaphragm pressure gauges are particularly suitable for connection of contacts.The series of diaphragm pressure gauges can be equipped with magnetic spring or inductive contacts. Inductive contacts are available for hazardous areas, assuming compliance with existing specifications. The selection of the contact versions depends on the process condition and the applicable safety requirements. Magnetic snap-action contacts are used in adverse operating conditions. The high contact pressure and the selection of various contact materials result in reliable and cost-effect solutions, above all when high currents have to be switched. Signal output does however take place slightly in advance of or lagging slightly behind the motion of the actual pointer value. Inductive contacts have an almost unlimited service, as the signal is switched without physical contact. Closing or opening takes place without any feedback effect on the measuring system, eliminating any signal lead or lag. A corresponding control unit is always required for operation. Units with inductive contacts may be operated in areas with potentially explosive atmospheres, assuming compliance with existing specifications.
