Abstract
An inductive pressure transducer senses fluid pressure within a tubular member by passing an alternating current within an inductor coil to generate a magnetic field. The magnetic field passes through a gap between the tubular member and the inductor coil, and into an exterior portion of the tubular member. A detector means senses the net energy transferred from the inductive coil by the magnetic field, which indicates the fluid pressure within the tubular member.
