Abstract (en)
[origin: WO2018165122A1] An apparatus includes a sensor body (206) and a sensor (204) configured to measure differential pressure. The apparatus also includes first and second coplanar pressure inputs in or on the sensor body, where the pressure inputs are configured to provide multiple input pressures to the sensor. Each pressure input includes a barrier diaphragm (208, 210) configured to move in response to pressure and an overload diaphragm (216, 218) configured to limit movement of the barrier diaphragm. First and second fill fluid (406, 408) may be configured to convey the pressures from the barrier diaphragms of the pressure inputs to the sensor as first and second input pressures. Passages (212, 402, 404) may be configured to transport the fill fluid between (i) gaps between the barrier diaphragms and the overload diaphragms of the pressure inputs and (ii) the sensor and gaps between the overload diaphragms and the sensor body.
