Abstract
The invention pertains to differential pressure transducers for gas turbine motors, for measuring variable pressure differences within a medium or between different media. The differential pressure transducer is constructed as a linear displacement sensor according to the linear variable displacement transducer (LVDT) principle, and has a ferromagnetic core that can be moved in a translatory manner, a spring element for the set position of the core given nominal differential pressure, a primary coil and two secondary coils arranged in succession axially over the length of the stroke range of the core, and a tubular housing having a delivery connection on both sides of the stroke area of the core.
