Prowave Ultrasonic Circular Proximity Sensor

The Prowave Air Ultrasonic Ceramic Transducers operate at a centre frequency of 32.8 ± 1.0 kHz, featuring a bandwidth of 1.0 kHz. They achieve a minimum transmitting sound pressure level of 113 dB at 32.8 kHz when driven at 10 Vrms from 30 cm. The receiving sensitivity is 67 dB at the same frequency. With a capacitance of 2400 pF at 1 kHz, they can handle a maximum driving voltage of 20 Vrms. The total beam angle is typically 33° at 6 dB, making these transducers ideal for specialized ultrasonic applications.
