The equipment described enables quick and accurate calibration of absolute, differential and gauge pressure transducers with range maxima between 350Pa and 35MPa (0.05 lb/in2 and 5000 lb/in ) and accelerometers with range maxima between l.Ogn and lOOgn.nBoth types of transducer are calibrated by subjecting them and an accurate reference transducer to a continuous sweep of input parameter. Graphs are drawn by an X-Y recorder of either the direct output of the transducer under test or its output suitably processed to show departures from the ideal nominal linear output.
