Abstract: Apparatus for effecting differential pressure sensitivity of a pressure measuring device. A pressure sealed housing having a relatively high pressure inlet connection contains an expansion bellows having a relatively low pressure inlet connection. The bellows'' free end moves in proportion to the pressure differential between the high and low pressure supply. A lever connected to the free bellows end to outward of the housing, transmits the bellows output force to an external pressure measuring apparatus.

Abstract: A transducer for converting motion displacement into a digital electrical signal. A radiation impervious vane or shield member secured to a motion producing device moves conjointly therewith in a motion path extending intermediate a predetermined radiation sensitive or emitting array pattern and a radiation source or sensor. Movement of the vane acts to interrupt the light beam between the source and sensor and the extent to which the beam is interrupted is a measured function of vane displacement. Continual updated logic count analysis of the array units interrupted by vane position produces an electrical digital output signal for remote utilization in correspondence to the logic count.
