Abstract
A device (1) for indicating the level of a dielectric fluid in a tank consists of a float (14) with an electric contact (15, 16) which moves along a tubular slide (11) wound round with a resistive wire (13), the slide consisting of a metal tube (11) coated with a layer of polyamide material with a high molecular weight, the thickness of the said layer being much the same as or rather greater than the diameter of the said resistive wire (13). The ends of wire (13) can be secured by embedding them in the polyamide. The tube (11) can be coated with epoxy resin paint under the layer of polyamide. The position of the turns of wire (13) relative to tube (11) is said to be more stable, e.g. with temperature variations, than with prior devices.
