PURPOSE: A zero point correcting device of a pressure transducer is provided to improve the safety of a patient by rapidly controlling the location of the pressure transducer. CONSTITUTION: A zero point reference unit(20) receives liquid(L) inside. The liquid received in the zero point reference unit is inputted to a conduit(30) through a discharge pipe(22). A cross sectional area(A2) of the conduit is smaller than a cross sectional area(A1) of the zero point reference unit. A zero point correcting unit(40) controls the height of the pressure transducer along a surface level(H2) of the liquid inputted to the conduit. The zero point correcting unit includes a lifting panel(42), a sensing unit(44), a holding plate(60), and a height control unit(70).
