Document Type and Number:
Japanese Patent JP2001518611
Kind Code:
A
Abstract:
A method of filling a measuring chamber of a transducer measuring a pressure or a pressure differential with a pressure transmission fluid through a filling channel is described.In this method, a filling pin having a longitudinal channel over part of its total length is inserted into the filling channel to the extent that there remains an open connection of the measuring chamber to the outside. After evacuating, the pressure transmission fluid which is under vacuum is introduced into the measuring chamber through the longitudinal channel under the influence of gravity, and then a supplementary amount of pressure transmission fluid is introduced into the measuring chamber by pushing the filling pin beyond the end of its longitudinal channel.
