Abstract
An electromechanical transducer unit for a field device includes a membrane embodied to execute mechanical oscillations, two rods perpendicular to the membrane and secured to the membrane, a housing, wherein the membrane forms at least one portion of a wall of the housing, and wherein the two rods extend into the housing interior, two magnets, wherein each magnet is secured in an end region away from the membrane to a different one of the two rods, and a coil with a core, wherein the coil is secured above the magnets within the housing, and is contactable with an electrical, alternating current signal, wherein the coil is embodied to produce a magnetic field that causes the two rods via the two magnets to execute mechanical oscillations, and wherein the two rods are secured to the membrane such that oscillations of the membrane result from oscillations of the two rods.
