Abstract
A pressure transducer utilizes a diaphragm made, for example, of ceramic or the like having upper and lower surfaces. One surface of the diaphragm receives an elongated thick film resistor. Circuitry is connected to the resistor for measuring any changes in resistance due to strains or forces applied to the resistor. Pressures applied perpendicularly to the longitudinal direction of elongation of the resistor produces high outputs in the form of changes in resistance which can be used to calculate strains in the longitudinal and transverse directions as well.
