APPARATUS FOR ZERO POINT COMPENSATING OF PRESSURE TRANSDUCER

摘要

PURPOSE: a kind of zero point correcting device pressure sensor is with the safety for improving patient, by rapidly controlling the pressure sensor at position. ;CONSTITUTION: zero reference unit (20) receives in liquid (L). The liquid gets zero reference unit and is input to pipeline (30) by discharge pipe (22). The cross-sectional area (A2) of conduit is less than the zero reference unit of cross-sectional area (A1). (H2) liquid is input to pipeline to the height of zero-point correction apparatus (40) control pressure sensor along the horizontal plane. Zero-point correction apparatus, including promotion panel (42), sensing unit (44), fixed plate (60) and height control unit (70). ;The 2012 of copyright KIPO submissions
