Abstract:
1. A force sensor assembly comprising: a housing; a load bearing member for receiving an input force to be sensed, said load bearing member having a first protrusion with round end for engagement with the coupling; circuitry for converting the input force into an output signal indicative of the input force; a coupling for transmitting the input force to the load bearing member, said coupling having a second protrusion extending centrally from a flange such that the distal end of the second protrusion engages the rounded end of the first protrusion from the load bearing member; a compressible reservoir containing dilatant fluid mounted between the housing and the flange to restrict the input force to the load bearing member caused by shock loading to the coupling, wherein the housing defines a recess for the circuitry, the rounded end of the first protrusion from the load bearing member extends proud of the recess for engaging the coupling.
