A housing for a capacitive sensor used in the measurement of pressure in a fluid, which capacitive sensor includes: a flexible ceramic diaphragm including a reference surface, a bottom surface, sidewalls, and a chamfered shoulder between said reference surface and sidewalls, and a pressure chamber open at the bottom surface, the reference surface being deflectable in response to a force acting in said pressure chamber; a capacitive sensor positioned so that its capacitance is varied as the diaphragm reference surface is deflected; wherein said housing comprises a lower member and an upper member connected to each other and enclosing the sensor; said housing lower member defining a recess for receiving the diaphragm sidewalls, and further defining a channel communicating with the diaphragm pressure chamber; and said housing upper member defines first and second portions of different diameters, and a shoulder between the first and second portions of different diameters, which shoulder abuts the chamfered shoulder of said flexible diaphragm.
