Abstract: A position detector includes an outer tube of having a magnetostrictive wire disposed therein. An electric circuit is mounted completely within the outer tube and is electrically connected to a pickup coupled to the magnetostrictive wire. A multi-pin connector is mounted at one end of the outer tube for coupling conductors extending from the circuit in the outer tube to external conductors. In an alternative embodiment, the position detector includes a threaded adapter threadingly mountable within an end wall of a pressurized fluid operated cylinder. Conductors extend from the circuit in the outer tube through the adapter to an external connector.

Abstract: A float for a liquid level detection apparatus including a tube extendable through liquid in a tank. The float is a buoyant body slidably mounted about the tube and having a diameter passable through an aperture in the tank. The float is preferably formed of two separate bodies joined by spacers positioned to allow the body to pivot from a first position substantially axially in line with the tube for insertion and removal of the float with respect to the tank to a second position substantially perpendicular to the tube in operative floating engagement with the liquid surface in the tank. The spacers, in one embodiment, are in the form of pins arranged in pairs along opposite side edges of the two bodies and spaced apart along the length of the two bodies such that the innermost pins of the two pairs of pins define an aperture for mounting the bodies transversely about the tube in the second, floating position.
