Abstract: A force measuring system for measuring the deflection force of spring-mounted magnetic reading and writing heads, and other parts, includes a capacitive type pressure transducer, of the type having two spaced insulating plates wherein at least one of the plates is a flexible diaphragm; a standardized pivoted force transmitting arm having one rounded end thereof engaging the center of said flexible diaphragm; a movable carriage for holding the magnetic head or other part to be tested under predetermined levels of deflection; guide plate arrangements for controlling the movement of the carriage so that the magnetic head or other part is brought into engagement with the end of the force transmitting arm; micrometer arrangements for providing a controlled amount of deflection of the reading head assembly or other part when the magnetic head engages the force transmitting arm; and measuring and display arrangements for indicating the force applied to the diaphragm at the predetermined level of deflection.
