ABSTRACT:
An in-line pressure transducer includes a body and an inner ring, coupled to the body, through which molten material flows. The inner ring expands in response to pressure from the molten material. An outer ring is located coaxially with the inner ring. At least one flexure connects the inner and outer rings. The flexures translate expansion of the inner ring to the outer ring. The body includes a cavity within which the outer ring is located. The cavity preferably has a cross-sectional shape that is trapezoidal in order to compensate for lateral displacement of the transducer in response to axial forces exerted thereon during operation.
