US 4,536,967 A · Tilt sensor and method of assembly

Abstract

An electrolytic type level sensor is secured atop spaced posts of a ceramic pedestal by applying epoxy only about the periphery of each post where it contacts the glass container of the level sensor and so that the glass container otherwise rests upon the posts. A thermal shunt of flexible braided copper is disposed about the glass container and is urged snuggly thereagainst by heat shrinking a plastic tube about the thermal shunt. The ceramic pedestal is received in an opening of a mounting plate and is urged by a spring pin against a "v" block type seat formed in the opening to establish points-of-contact therebetween. Epoxy is applied between the pedestal and opening to secure same together except at said points-of-contact. Plastic insulation is disposed about the sensor and pedestal and otherwise fills spaces in a housing for same and attached to said mounting plate.

Dependent claims

A tilt sensor;

comprising:
(a) mounting means;
(b) pedestal means secured to and extending from said mounting means;
(c) level sensor means secured to said pedestal means and having an exterior surface;
(d) thermal shunt means dispsosed about and in close proximity to said level sensor means and urged into close contact with said exterior surface of said level sensor means;
(e) said level sensor means containing a fluid electrolyte disposed therewithin to form a bubble of predetermined size and configuration and which is disposed at a predetermined location therewithin when the tilt sensor is in a predetermined position with respect to a given reference;
(f) said level sensor means further including conductive means suitably connected to said level sensor means for providing an output signal indicative of movement of said level sensor means with respect to said given reference.
