ABSTRACT:
Apparatus is disclosed in which a digital display is driven by an electronic output generated in response to field changes which occur when a transformer interacts with a magnetic core driven in a linearized path by a curved Bourbon tube in response to applied ambient pressure. The transformer is a simple variable transformer and the core is configured to follow a radial path within the field of the transformer.
