Prowave Ultrasonic Circular Proximity Sensor, 3 → 750 cm Detection

The Prowave Air Ultrasonic Ceramic Transducers operate at a centre frequency of 32.8 ± 1.0 kHz, with a bandwidth of 2.5 kHz. They provide a minimum transmitting sound pressure level of 115 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, these transducers can withstand a maximum driving voltage of 20 Vrms. The typical total beam angle is 100° at 6 dB, making them suitable for various ultrasonic applications.
