Level Transducers

Airmar’s multi-use ultrasonic air transducers provide reliable, maintenance-free measurement of liquid and solid levels. Safe, compact and rugged, AIRDUCER® transducers provide proven non-contact level sensing performance and are key components of measurement sensors and systems on equipment such as tanks, asphalt pavers and agricultural machinery.

Airmar ultrasonic air transducers are ideal for a variety of environments and, unlike most alternative measurement solutions, can detect clear, transparent or shiny objects, and are unaffected by color. Manufactured in the USA, they have a sealed housing for lasting reliability. One-piece PVDF housing is also available for chemically aggressive environments and food (3A) sanitary applications. Check out Airmar’s full range of ultrasonic transducers for level measurement.

Key Features:

  • Multi-use capabilities for a wide variety of applications
