1. A guided-beam transducer, comprising:
- a transducer body;
a beam having one end section fixed to said body, an opposite end section adapted to receive a load normal to the beam acting to deflect same, and an intermediate section joining together said two end sections;
each of said two end sections being formed with opposed edges that converge towards each other along straight lines crossing at the centre of the beam;
means for guiding the deflection of said beam; and
a strain gage bonded to each of said two end sections within the opposed converging edges thereof.

Abstract
Described is a dual guided-beam transducer provided with constant-strain characteristics by forming the two end sections of each beam with opposed edges that converge towards each other along straight lines crossing at the center of the beam, the strain gages being bonded to the end sections within their opposed converging edges.
Two embodiments of the invention are described. One embodiment includes a body mountable to a fixed support in cantilever fashion with the load applied normal to the axis of the support. A second described embodiment is a folded-end transducer of cylindrical shape for accommodating loads applied axially to the cylinder.

8. A guided beam transducer, comprising:
- a transducer body formed with a bore extending transversely therethrough;
a first slit extending through one side of the body at right angles to the longitudinal axis thereof spaced from one end of said bore and terminating short of the opposite side of the body;
a second slit extending through the opposite side of the body parallel to said first slit, said second slit being spaced from the opposite end of said bore and terminating short of said one side of the body;
said bore and slits being configured to define a pair of spaced parallel beams formed integrally with said sides of the body normal to the longitudinal axis of the body with the body having folded ends for receiving loads applied parallel to the longitudinal axis of the body; and
a strain gage bonded to the ends of each of said beams on the faces thereof facing said slits;
an axial bore being formed through each of said folded ends concentric with said longitudinal axis of the body, said axial bores terminating at the slit at the respective end of the body and being of a diameter to expose therethrough substantially the complete span of the respective beam and the strain gages bonded thereto. - View Dependent Claims (9, 10)
