A transducer sensing element isolation assembly including a pressure housing having a chamber in which the sensing element is disposed, which sensing element communicates with the interior of a bellows through a sealing element disposed between the pressure housing and a base on which the bellows is secured. The chamber, bellows interior and sealing element are filled with a dead volume of low compressibility, low thermal expansion isolation fluid. The bellows is contained in a replaceable bellows capsule which is threaded into a bellows capsule cavity into which the chamber communicates, and the sealing element is maintained in place by the capsule being made up into the cavity.
