Abstract: A strain gauge pressure transducer comprising a housing having an internal pressure cavity across which is mounted a flexible elastomeric diaphragm that separates high and low pressure chambers in the gauge that the housing is arranged to separately connect the sources of high and low pressure, respectively. A range spring in the form of a leaf spring is anchored to the housing cantilever fashion in the high pressure chamber and to one side of the diaphragm to dispose the live length of same, as defined by a clamp device, in overlying relation to the diaphragm, to which the leaf spring live length is connected for deflecting movement thereof by the diaphragm.
