Abstract
A pressure transducer for the measurement of mid-range pressures in the preferred range of 500-7500 psi and including an elongated frame having a capillary tube extending therethrough and employing a coupler at one end of the frame for sensing input pressure. A sensing member is provided at the other end of the capillary tube and has a sensing chamber adapted to have at least one filler means disposed therein. A recess is provided in the sensing member defining a relatively thin wall adjacent the sensing chamber. This wall has a pressure responsive sensing surface that extends substantially parallel to the capillary tube length and upon which strain gages are secured.
