CONTROLLED DIFFERENTIAL VOLUME CONVERTER

摘要

This design applies to the differential volume converter used especially in connection with sensors that use the time variable air pressure as propellant medium. It is supposed to be used for coulometric measuring. The design configuration makes use of the step engine, on whose shaft the eccentric and the diaphragm of the position sensor are arranged. When rotating the eccentric, the motion is transmitted to the link and via its functional surfaces to profiled membranes. This motion results in volume changes between the profiled membranes and covers, while the volume changes are in the phase opposition. These changes connected with chambers of the linked sensors convert into pressure changes that is used for the drive of sensors.<IMAGE>
