Methods, systems, and devices for detecting and quantifying pressure and pressure changes within a system are provided. In one aspect, a pressure sensing device is provided that includes a sensing tube having an interior volume and at least one wall, the wall being configured to deform in response to an external pressure that is greater than an external pressure threshold. The at least one wall is further configured to deform as a function of the external pressure. The device may also include a transducer operably coupled to the sensing tube, the transducer being configured to detect changes in the interior volume as a result of deformation of the at least one wall.
