ABSTRACT OF THE DISCLOSURE A pressure transmitter housing for mounting an internal sensing cell , and having two sections that provide integral pressure connecting flanges for differential pressure sensing, and provide proper clamping pressure and seals on the sensing cell . The housing sections also provide a space for all transmitter circuitry in a toroidal chamber defined in the housing and surrounding the sensing cell . Each of the housing sections has a sealing surface for sealing against the outer ends of a differential pressure sensing cell , and clamping the ends of the cell together under compressive load using external clamping bolts . One of the housing sections has a terminal strip to connect to external power supply wires. The housing sections are easily cast and machined, and will accommodate the necessary dimensional tolerances needed for manufacturing processes in making the sensing cells. Low cost manufacturing is achieved by combining the function of the sensing cell, clamping flanges and circuit housing, and at the same time providing the necessary pressure connection flange functions.
