Abstract
For identifying the position of a movable body comprising a reflector, a primary transducer and a secondary transducer are utilized which transmit ultrasonic pulses to the reflector and, in turn, detect the ultrasonic pulses reflected by the reflector. A measuring device identifies a positional value assigned to the position of the reflector from the transit times of the ultrasonic pulses from both transducers. To this end, the measuring equipment has a primary control to which a calculator, a primary memory, a timer and a pilot control are coupled. Furthermore, the measuring equipment has a receiver, a transmitter and a transfer device which alternately connects the ultrasonic transducers to the measuring equipment.
