ABSTRACT:
A housing with a fluid flow bore is provided with an integral diaphragm forming a cavity within the housing to position the diaphragm adjacent the bore, for receiving sensors thereon to receive intelligence from the housing indicative of any one or all of a plurality of physical functions related to strain in the housing such as by way of example, pressure of fluid in the bore of the housing, axial load, torsion, shear or bending and communicate or transmit the intelligence of such functions to a predetermined location. Where desired, the cavity may be precharged with an inert gas to inhibit damage to the sensors and to serve as a reference pressure. The cavity and transducer therein are isolated from ambient conditions externally of the housing. A flow conduit may be connected at each end of the housing to conduct fluid to the housing bore. Where necessary the intelligence relating to the function or functions may be compensated for temperature or second order effects related to any or all of the functions.
