Abstract
A device for measuring pressure between two cylinders of a press includes a plate mounted to the end of a journal of one of the cylinders in a position perpendicular to the cylinder axis, and a set of electrical proximity sensors measuring the tilting of the plate as a result of slight bowing of the cylinder in response to changes in applied pressure. The proximity sensors are disposed at diametric locations at a substantial radius with respect to the cylinder axis, and an electrical circuit combines signals from the proximity sensors in such a way as to cancel signals generated in response to axial shifting of the cylinder to which the plate is mounted. Preferably the sensors are mounted in the common plane including the two cylinders and a set of sensors is disposed on each side of the plate. Additional sensors can be used to independently measure the pressure applied by a third cylinder engaging the cylinder to which the plate is mounted.
