Latest Patents

Rezendes' latest patents include a transducer assembly that provides position output proportional to electrical input. This electro-pneumatic current-to-position transducer features an electric motor with a permanent magnet for a stator. A spring-restrained coil is pivotally suspended about the magnet, functioning as a rotor. When an input current is applied to the coil, it induces mechanical rotation proportional to the current. A flapper, fastened to the coil, moves toward the nozzle of a pneumatic circuit, altering the back pressure. This change is amplified and sensed by pressure-responsive devices, which feed back to a control lever, maintaining a constant separation between the flapper and the nozzle. The pressure signal developed serves as a pneumatic output for various applications. Two embodiments of the transducer are disclosed, one converting input current into pressure output and the other controlling the position of a process control valve stem.
