Airmar Technology Corporation

Airmar develops and manufactures the most reliable non-contact ultrasonic air transducers for use in today’s demanding commercial and industrial applications. Our AIRDUCER® transducers are the go-to choice for system integrators who demand outstanding quality and unsurpassed performance from every component. 

Our multi-use transducers are critical components in the development of a myriad of sensors and measurement systems in fields requiring liquid or solid levels, flow control, automation control, proximity sensing, obstacle avoidance, distance measurement and inventory control.

Safe, compact and dependable, Airmar transducers are ideal for a variety of environments and deliver proven non-contact sensing performance from equipment such as asphalt pavers, agricultural machinery and water/wastewater systems, as well as many other challenging applications. Most environments are no match for our transducers’ sealed housing, but for especially caustic applications, our one-piece Kynar® PVDF housing option is the best solution.

Built for lasting durability, Airmar’s rugged air transducers are rated IP68 and, with no moving parts to wear out, no maintenance is needed.
