The Prowave Air Ultrasonic Ceramic Transducer operates at a centre frequency of 40.0 ± 1.0 kHz, with a bandwidth of 2.0 kHz. It has a minimum transmitting sound pressure level of 115 dB at 40.0 kHz, measured as 0 dB re 0.0002 μbar with 10 Vrms at 30 cm. The receiving sensitivity is 67 dB min, corresponding to 0 dB equals to 1 volt/μbar. The capacitance at 1 kHz is 2400 pF ± 20%, and the maximum continuous driving voltage is 20 Vrms, with a typical total beam angle of 85° at 6 dB.

Aluminium housing
Function effectively in temperatures ranging from 30 to 80 °C
