Abstract
A fluid pressure transducer having a hollow enclosure with an elongated tubular guide supported therein around which a tubular piston moves in response to fluid pressure forces acting on one piston end. A spirally-wound wire resistance coil on the guide is contacted by one end of a conductor carried by the movable piston to effectively charge resistance through the conductor and parts of the coil. The conductor is connected to one end of a metal spring which opposes piston movement due to pressure forces. An opposite end of the metal spring is connected to a terminal to transmit the resistance changes.
