Abstract
A pressure transducer comprises a movement which has separate span and set-point calibrations. A subsequent calibration of the span does not adversely influence a previous calibration of the set-point. Sensed pressure is reflected as arcuate motion of a crank mechanism along a resistor. The span calibration is performed by adjusting the position of the resistor in relation to the crank's pivot. The pivotal mounting of the crank is provided by a pivot member disposed within a slot. Adjusters in transverse slots which intersect the pivot mounting slot act upon the pivot member to establish the set-point calibration. The transducer is especially well suited for fabrication and calibration by automated equipment.
