Abstract
An electronic transmitter for transmitting pressure values of industrial process fluids includes an inductive sensor employing a measuring diaphragm which is movable as a function of the pressure changes in the process fluids so as to produce corresponding changes in inductance and therefore corresponding signals which are suitably processed in an associated electronic circuit. The measuring diaphragm is provided with a rigid center forming or carrying one or more elements of a material exhibiting high magnetic permeability.
