Abstract

Electrical connections to thin film coatings, especially useful in a fluid flowmeter, have a conductive coating pressed against a rigid, relatively long, connector bar by conductively coated pads of elastomeric material at a selected controlled pressure, with the electrical connections to the film coating being made through the bar and pads. Utilizing this method, localized high stress areas which cause damage to the thin film are avoided, and low current densities are accomplished by the controlled contact pressure over a large area of the film coating.
