Abstract: In one embodiment, a sensor assembly has a magnetostrictive (MS) element (20, 52, 76, 96, 108, 126) and a sensor housing (18, 50, 70, 98, 106) defining at least one active wall (28, 68, 80, 103, 116). 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 adj acent the active wall by sliding the MS element into an end of the sensor channel in a direction parallel to the active wall.
