A transducer responsive to pressure or force, comprises a diaphragm secured around its periphery to the housing of the transducer and having a cup-shaped portion formed concentrically therein. Means are provided for applying, in use, a pressure or force to one surface of the diaphagm and means responsive to the resulting deflection of said diaphragm for providing an indication of the applied pressure or force. Strain gauges are mounted on an annular portion of the diaphragm which extends between the cup-shaped portion and the periphery of the diaphragm. An overload protection device may be provided to limit deflection of the diaphragm.
