ABSTRACT:
A transducer diaphragm overload protection system provides a core of insulating material for supporting a sensor and being movable relative to a deflectable diaphragm portion, and establishes a mechanical interconnection between that deflectable portion of the diaphragm and that movable core, while that core is in a movable condition. The movable core is rendered stationary relative to the diaphragm, and the mechanical interconnection is removed by establishing between the deflectable diaphragm portion and the core a gap corresponding to a predetermined diaphragm deflection, while maintaining the core stationary relative to the diaphragm. Advantageously, in pressure transducers having a ceramic core for supporting the transducer sensor, the desired gap may then be established by locating a dissolvable shim between the core and the diaphragm, while such core is movable, and by thereafter dissolving such shim after the core has become set in the transducer. Alternatively, the diaphragm may be deflected by application of an overpressure, whereby the core is moved into the desired position, and the necessary gap may thereafter be established by relaxing the diaphragm after the core has become set in the transducer.
