摘要
The transducer converts a d.c. voltage into a variation in hydraulic resistance. A dielectric fluid is pumped through an annular channel between a pipe which acts as an outer electrode and a rod which acts as an inner electrode. The ends of the rod are rounded, and when the applied voltage is zero, the liquid flow is laminar. The rod may be supported by insulating spiders at its ends and has longitudinal wires of dielectric material lying in grooves in its surface. When a voltage is connected across the two electrodes, an electrostatic field is set up which causes the fluid flow to become turbulent, and the pressure drop at a given flow rate is increased. The pressure drop is measured by manometers.
