The present invention improves upon prior art pressure sensors by providing a noninvasive pressure sensing assembly capable of accurately indicating relatively minute pressure changes. The present invention generally includes separating a pressure chamber from a pressure transducer by a thin, compliant membrane. The unique shape of the membrane assures that minute movements in the membrane are transferred to the measuring pressure transducer. Any change in pressure within the chamber will vary the amount of force exerted by the membrane against the transducer which, when any preload is deducted, will indicate the pressure within the chamber.
