AT75 Airducer® Transducer
Non-contact level, flow and distance measurement is reliably delivered by the ultrasonic AT75. It includes rugged sealed construction, and PVDF housing is available for more chemically aggressive environments. The AT75 is available with compete assembly or in a kit version, and is also available as an AR model with threaded cap. It operates at 75 kHz and its sensing range is 20 cm to 10 m.
