Example apparatuses and systems for a combined temperature and pressure sensing device with improved electronic protection are provided. An example apparatus includes a media isolation chamber assembly having a sleeve member and a bellows member, a first circuit board element disposed in the bellows member and encapsulated by insulator media in the bellows member, a pressure sensing element disposed in the bellows member and electrically coupled to the first circuit board element; and a temperature sensing element disposed in the sleeve member and electrically coupled to the first circuit board element.

The present invention provides a sensor system for measuring a parameter (e.g. volume, temperature or pressure) of a target, the system comprising a diaphragm, a sensor for measuring the axial spacing between the sensor and the diaphragm, and an axially adjustable mount. The mount has a first axial end for mounting the diaphragm which is axially movable relative to the sensor and an opposing, second axial end which is axially fixed relative to the sensor. The diaphragm and mount define a chamber for receiving the target or for being received within the target. In use, the axial spacing between the first axial end and the second axial end of the mount and thus the axial spacing between the diaphragm and sensor varies as a result of a change in the parameter differential across the diaphragm.
