The equipment described enables quick and accurate calibration of absolute, differen tial and gauge pressure transducers with range maxima between 350P a and 3~~Pa (0.05 lb/.1~~ ~ and 5000 lb/~.n 2) and accelerometers with range ‘ maxima between I.Og and 100 ~.-/A / ’. i Both types of transducer are calibrated by subjec ting them and an accurate reference transducer to a continuous sweep of input parameter. Grap hs are drawn by an X—Y recorder of either the direct output of the transducer under test or its outpu t suitabl y processed to show departures from the ideal nomina l linear ~ 1 NYu U~I.
