A pressure transducer is disclosed wherein no wetted areas have been welded. A cavity is milled into the back of each of the blocks of a material which will make up the body of the transducer. Pickup coils are placed into these cavities and are held in place generally with epoxy cement. With the coils mounted within the sensor body, the surface which will be exposed to the sample or reference fluids is comprised of a single, solid material with no welding joints. Further, as the sensor block half is made of a single, solid material, fluid fitting connections may be machined directly into the body. The pickup coil placed within the improved sensor body may be wound on an open frame of nickel superalloy (NiSA). Another embodiment involves coating or encapsulating the sensing membrane within a soft, non-magnetic material protecting it from corrosion.
