Magnetostriktiver Ultraschallwandler NP-40

Ultrasonic transducer is a device that converts energy into ultrasound 18... 25 kHz. Ultrasonic transducer switches back and forth many times a second between acting as an actuator for producing ultrasonic waves. Inside the sensor contains coils of wire, wound on opposite sides of the ring, made of many thin sheets of high-performance magnetostrictive material "permendur".
