Magnetostrictive sensor

摘要

An improved mounting arrangement is shown for a magnetostrictive level sensing instrument for sensing level of a process fluid in a process vessel. The process vessel includes an opening into a storage space in the vessel. The improvement includes an elongate tube having a closed end and an opposite open end. A process fitting receives the open end of the outer tube, the process fitting being adapted to be received in the vessel opening, in use, whereby the process fitting and the elongate tube seal the vessel opening. A magnetostrictive wire assembly is removably received in the elongate tube through the open end for operatively sensing position of a magnetic float captured on the elongate tube and floating atop the fluid in the vessel. A housing is mounted to the adaptor fitting and supports the wire assembly when the wire assembly is received in the tube.
