METHOD FOR FILLING THE MEASURING CHAMBER OF A TRANSDUCER MEASURING PRESSURE OR PRESSURE DIFFERENTIAL WITH A PRESSURE TRANSMISSION LIQUID AND A PRESSURE OR PRESSURE DIFFERENTIAL MEASURING TRANSDUCER

摘要

The invention relates to a method for filling the measuring chamber (4, 13, 27) of a pressure differential measuring transducer with pressure transmission liquid via a filling duct (27). According to the inventive method, a filling bar (29) having a longitudinal duct (51) along part of its total length is inserted into the filling duct (27) to such a degree that a connection of the measuring chamber (4, 13, 27) remains open to the outside. After evacuation, the under-pressurized pressure transmission liquid is fed by gravity into the measuring chamber (4, 13, 27) via the longitudinal duct (51). An additional amount of pressure transmission liquid is subsequently fed into the measuring chamber by pressiing the filling bar (29) inwards via the end of the longitudinal duct (51).
