Product Introduction

The working principle of the Danish API ultrasonic level switch is based on the transmission principle of ultrasonic waves in a metal rod. The piezoelectric sensor is installed at one end of a cylindrical metal rod (waveguide rod), emitting pulses that move in the waveguide rod like sound waves. Under the action of this force, the sensitive area located at the other end of the metal rod begins to oscillate, and the reflected wave generated by the oscillation returns to the sensor, which then converts it into an electrical signal.
