This lecture covers the principles of piezoelectric sensors, focusing on the need for proper amplifier assembly due to the sensor's characteristics. It discusses voltage and charge amplifiers, compensation techniques, and frequency responses. Additionally, it explores ultrasonic distance sensors, including their applications in level measurement, flow sensing, and bubble detection. The lecture delves into the working principles of ultrasonic technology, such as pulse trains, magnetostriction, and correlation measurements for distance estimation.
