High Performance, Maintenance Free Ultrasonic Transducers.

ABM’s transducers and drivers have been designed and engineered to overcome the known challenges of utilizing ultrasonic technologies for level and distance measurement.

Technology Advantage

  • Very uniform polar pattern, negligible side lobes
  • Very uniform near field
  • Very wide frequency bandwidth that produces uniform echoes, short ringing and wide temperature operation
  • No housing influence on transducer operation
  • No mounting influence on the transducers performance
  • Self-cleaning face due to a highly active driver – removes condensation and any other solid build-up
  • Performance in the transmit and receive modes is not temperature dependant
  • No influence of thermal shocks on the transducers materials
  • Transducer face can be covered by any material (i.e. PVC, Teflon, 316L stainless steel and more)
  • Built-in temperature compensation
  • Compact sizing to fit in tight places
  • Matching to any partners pulse transceiver
  • In addition to our advanced technologies, we provide our
