METHOD AND DEVICE FOR DISCRETE DETERMINATION OF THE RELATIVE POSITION OF AN ACCUMULATOR'S DEVIDING PISTON

摘要

A method of and device for determining the position of a dividing piston (8) in an accumulator (1), the dividing piston (8) being magnetized by at least one magnetizing coil (22), and that the magnetic field of the dividing piston (8) is measured by a sensor coil (24) proximal to the dividing piston (8), the signal from the proximal sensor coil (24) being compared with a signal from a sensor coil (24) located at a distance from the dividing piston (8).
