Ultrasonic Air Transducer Technical Data Sheet Airmar ultrasonic transducers deliver the highest level of performance in the most challenging environments and they are the key component for our customers success and their applications. Our precision tuned air-ranging transducers are tried and true performers, even when used for difficult tasks. American-made from the highest quality materials, Airmar’s ultrasonic transducers provide reliable, long-lasting excellence to any measurement system. 30 kHz AIRDUCER® Ultrasonic Transducer Applications • Level measurement • Proximity • Obstacle avoidance • Traffic control Best Operating Frequency: 30 kHz, ±4% Minimum Transmit Sensitivity at Best Transmit Frequency: 105 dB re 1μPa/V at 1 m Minimum Receive Sensitivity at Best Receive Frequency: -155 dB re 1V/μPa Minimum Parallel Resistance: 700 Ω, ±30% Minimum and Maximum Sensing Range*: 60 cm to 30 m Typical Sensing Range: 80 cm to 25 m Free (1 kHz) Capacitance: 5,700 pF, ±20% pF Beamwidth (@ -3 dB Full Angle): 12°, ±2° Maximum Driving Voltage (2% Duty Cycle Tone Burst): 2,200 Vpp Operating Temperature: -40°C to 90°C Weight: 800 g Housing Material: Glass filled polyester Acoustic Window: Glass reinforced epoxy Features • Rugged sealed construction • Housing design will accommodate transceiver and signal processing electronics • Standard internal shielding Options • Cylinder housing available with mounting cap kit • Cable length can be customized • Mounting cap available in BSP, NPT, or M32 threads • 10 KΩ thermistor available for temperature compensation • Available in PVDF housing for use in chemically aggressive *Pulse-Echo Mode: Minimum and maximum ranges are best case scenarios. Actual range may vary, depending on drive circuitry and signal processing. Note: Optimally, performance measurements should be taken when the ransducer t reaches a steady state. Thread Choices: 1" tapered BSP x 0.75" long 1" NPT x 0.94" long (ref.) M32-1.5 x 0.75" long Impedance Magnitude & Phase Transmit & Receive Voltage Response May be shown with optional equipment. Additional Resources Theory of Operations Applying Ultrasonic Technology Airmar’s T1 Developer’s Transceiver Module can be used for evaluation of AIRDUCER® Transducers. ©Airmar Technology Corporation AR30_rT 04/11/24 As Airmar constantly improves its products, all specifications are subject to change without notice.
