The report describes the initial design, construction and development of a diaphragm type pressure balancing transducer which uses the electromagnetic J x B force to balance the applied fluid pressure. The pressure is measured by the direct substitution of electromagnetic pressure and a measurement of the current required to produce the balancing pressure. This technique for pressure measurement results in a direct pressure measurement by substitution and is independent of the tension and elastic constants of the pressure sensing diaphragm provided positive tension is sustained in the diaphragm.
