Pressure sensor |
摘要 |
Fatigue fractures in the bellows capsule of a bellows-type pressure sensor are prevented by wrapping the capsule with a vibration damping material such as an open cell polyurethane foam saturated with a fluid. In the preferred embodiment, wherein the sensor is employed in a gas turbine engine fuel control, the fluid may conveniently comprise liquid jet engine fuel.
