4. Industrial applications

Electropneumatic power modulators are used in the much more general context of continuously controlled electropneumatic systems. The term refers to a technology for components and processes that use pressurized air as a power transmission element, with continuous control provided by electrical quantities. This technology is often misleadingly referred to as "proportional pneumatics". These systems are based on the synergy of disciplines such as automation, electronics, computer science and fluid and solid mechanics, and therefore meet the definition of mechatronic systems. Briefly, a continuous electropneumatic system consists of a device supplying and transporting the energy of the gaseous fluid, an electrically controlled power modulator, an actuator transforming the free energy of the fluid into mechanical energy, sensors and a processing and communication unit. The advantages of this...
