摘要： In one embodiment, a sensor assembly has a magnetostrictive (MS) element and a sensor housing defining at least one active wall. A sensor channel is disposed on a first side of the active wall, with the MS element being disposed in the sensor channel and closely received therein. A fluid is on a second side of the active wall, and the active wall is the wall through which stress from pressure of the fluid causes stress on the MS element. The sensor channel defines an axis parallel to the active wall, and the MS element is positioned adjacent the active wall by sliding the MS element into an end of the sensor channel in a direction parallel to the active wall.

摘要： A strain sensor includes a load carrying body configured to strain in response to a load applied along a load path. The sensor further includes a magnetostrictive electrical conductor affixed to the body but out of the load path. Application of the load causes the body to strain, which in turn results in a proportional stress being imparted to the magnetostrictive conductor, altering its magnetic permeability. A circuit is electrically connected to the conductor to detect such changes in permeability, which are indicative of the applied load.
