Gladiator Acoustic Switch

Gladiator Acoustic Switch

The Gladiator Acoustic Switch can be used for blockage detection, barrier detection, machine detection / protection and point level measurement, and detection of objects or material between two points.


  • Blocked chute detection in wet or dry environments
  • Wet screen blocked chute detection
  • Nucleonic / tilt switch replacement
  • High level alarm / Low level alarm
  • Truck / machine detection (ROM bins, Primary Crusher Dump Pockets)

Principle of Operation

The Gladiator Acoustic Switch uses Acoustic Wave technology in a new Sender / Receiver form for blocked chute detection and anti-collision for heavy machinery. The Gladiator Amplifier powers two AW Transducers which use special HAWK developed software where both units pulse and receive each otherÍs Acoustic echoes. When the path between the Transducers is blocked, the units immediately detect the presence / absence change of the return signal and trigger a communications relay for indication or control purposes. The Transducers work both together and independently to detect pulse interference giving twice the application security. HAWKÍs Acoustic Wave Transducers are self cleaning. The Acoustic Switch is designed for continuous operation in dusty, wet environments where other technologies fail. The power of each pulse (pressure wave) blows the water, moisture and build-up off the face of the diaphragm.
