ABSTRACT:
A transducer adapted for load cell applications comprises a base having a load receiving member connected thereto by at least one and preferably two flexure springs to permit the member to flex relative to the base. A sensing beam, having one or more strain gauges secured thereon, is mounted in cantilevered relationship on the base and has a free end positioned adjacent to the member for engagement therewith to sense the load imposed on the member to produce a variable electrical output signal in response to the magnitude of the load. An adjustment is preferably provided to selectively adjust a point whereat a sensing tip mounted on the member engages the sensing beam whereby the output signal can be selectively adjusted to vary the weight capacity of the transducer.
