A pressure sensor including a housing having an interior surface forming a cavity, and a fill passageway communicating with the cavity. The fill passageway has opposite ends defining an axis extending between the ends, and one of ends defines a fill port spaced from the cavity. A pressure transducer is mounted on said interior surface. The pressure sensor also includes a sealing member moveable across the fill port in a direction transverse to the axis between a first position allowing fluid flow through the fill passageway and a second position closing the fill passageway such that the fluid is sheared off at the fill port to seal said cavity. Preferably, the fluid pressure within the cavity before sealing is substantially equal to the fluid pressure within the cavity after sealing.

Method and apparatus for sealing a pressure transducer within a housing

A temperature sensor assembly for measuring ambient temperature and including a housing defining an enclosure. A temperature sensor is mounted within the enclosure. The housing includes a brass cap and a liner for conducting heat from the brass cap to the temperature sensor. The temperature sensor is mounted on the brass liner and is electrically insulated from the brass liner by a thermally conductive material.

Apparatus for containing a temperature sensing device

A variable reluctance magnetic speed sensor senses the speed of a rotating gear (12). A ferrous outer cylindrical shell (22) extends axially and has a magnet (14) at one axial end and a coil (16) at the other axial end. An inner pole piece (4) in the coil (16) directs magnetic flux across a gap to the gear teeth (10), which flux is returned by the outer pole piece shell (22) to the magnet (14). Particular pole piece gap spacings are disclosed together with various pole piece constructions.
