ULTRASONIC TRANSMITTER OF DEVIATION ANGLE FROM VERTICAL WITH FREQUENCY OUTPUT Russian patent published in 2003 - IPC

Abstract RU 2212631 C1

FIELD: instrumentation engineering, measurement of deviation angle of various objects from vertical line. SUBSTANCE: transmitter includes case with cylindrical chamber, ultrasonic detector, ultrasonic radiator, amplifier and frequency meter. Chamber is filled with two immiscible liquids with different densities. Ultrasonic detector and ultrasonic radiator are positioned in case at same angle with respect to its base and are conjugate one relative another by means of interface of liquids. Output of amplifier is connected to frequency meter. Ultrasonic radiator is connected to output of amplifier. Liquid into which ultrasound is emitted functions as resonator that determines self-excitation frequency of amplifier. EFFECT: improved metrological characteristics and raised accuracy of processing of measurement signals. 1 dwg
