发明名称 HYDRAULIC CELL FOR CALIBRATING A PRESSURE TRANSDUCER
摘要 A hydraulic cell is used for calibrating an electro-mechanical pressure transducer. The transducer is positioned in the cell between an opposed pair of free-floating pistons. Calibration pressures are uniformly exerted upon the transducer by forcing the pistons toward one another with pressurized fluid injected into pressure chambers behind the pistons.
