Applications:

Level sensors are typically divided into two different measuring systems: Propagation time measurement of a reflected airborne ultrasonic signal by Piezo-ceramic transducers on the one hand, and immersed transducer measurement by piezo-ceramic sensors on the other. The self-resonant frequency of a metal tuning fork is excited by a small piezo-ceramic plate. This self-resonant frequency depends on the surrounding medium. If for example the tuning fork is immersed in a liquid or a powder, the resonant frequency of the system will change. This change in frequency is detected by the evaluation electronics. The disadvantage of this system is that no analog measurement is possible. The sensor only indicates whether it has exceeded or fallen short of a certain level. This drawback can be overcome by positioning several of these sensors at different levels in the tank. The advantage of the system is that the existing substance is very reliably detected and the sensor is largely insusceptible to interference.
