Abstract: A pressure transducer body is described which has a bore running its length and contains (a) a means for receiving a pressure transducer, (b) a fluid reservoir, (c) a stationary elastic plug member having embedded therein a T-shaped rigid pin member, and (d) a chamber for receiving a fluid under pressure. The elements of the transducer body are combined in such a way that pressures of fluids flowing into chamber (d) are accurately measured using conventional pressure transducers even at very high pressures (e.g. 20,000 psi). More importantly, perhaps, the configuration of the transducer body permits accurate pressure measurements on pressurized fluids which are corrosive and/or abrasive. This makes the pressure transducer bodies particularly useful in the oilfield service industries for measuring the pressure of acidizing or hydraulic fracturing fluids used in stimulation.
