Abstract
A sensor for measuring the density of a magnetic porous material such as foam. The sensor includes a load cell connected to a magnet. The magnet is spaced a predetermined distance away from the material. The load sensed by the pull of the magnet is translated into a perceivable density value.
Claims8
An apparatus for measuring the density of a metal plated porous foam sample, the apparatus comprising a magnet, the magnet connected to a load cell, means for maintaining the magnet a fixed distance away from the sample, the load cell adapted to produce an output signal that is a function of the density of the sample, and the output signal of the load cell connected to a density display device.
A method for determining the density of a metal plated porous foam material including:
- a) placing a magnet a fixed distance away from the material;
- b) measuring the force experience by the magnet vis-a-vis the material by a load cell;
- and
- c) translating the resultant force into a density value of the foam.
