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. 50 kHz AIRDUCER® Ultrasonic Transducer Applications • Level measurement in chemically aggressive environments • Food and beverage processing • Flow monitoring Best Operating Frequency: 50 kHz, ±4% Minimum Transmit Sensitivity at Best Transmit Frequency: 105 dB re 1µPa/V at 1 m Minimum Receive Sensitivity at Best Receive Freq.: -170 dB re 1V/µPa Minimum Parallel Resistance: 350 Ω, ±30% Minimum and Maximum Sensing Range*: 30 cm to 15 m Typical Sensing Range: 35 cm to 10 m Free (1 kHz) Capacitance: 5,000 pF, ±20% pF Beamwidth (@ -3 dB Full Angle): 10°, ±2° Maximum Driving Voltage (2% Duty Cycle Tone Burst): 1,000 Vpp Operating Temperature: -40°C to 90°C Weight: 250 g Housing Material: Kynar® 720 Acoustic Window: Kynar® 720 • Rugged one-piece PVDF housing is U.S. FDA compliant • hreaded design allows for installation in various pplications T a • Standard internal shielding Options • Nut—2" BSP thread • omplete assembly available with standard cable lengths C • 0 KΩ thermistor available for temperature ompensation 1 c • 12 mm extension sleeve • Mounting caps available in BSP, NPT, or M32 threads • Optional PCB standoff configuration lengths available Impedance Magnitude & Phase Housing design will accommodate transceiver and signal processing electronics Transmit & Receive Voltage Response Compatible With: 2” BSP / NPT universal thread 2-11 BSP Directivity Pattern Thread Options: 1" tapered BSP x 0.75" long 1" NPT x 0.94" long M32-1.5 x 0.75" long *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 t ransducer reaches a steady state. 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 ARK50THD_rU 04/11/24 As Airmar constantly improves its products, all specifications are subject to change without notice.
