Hawk Gladiator - General Description and Features; Principle of Operation

Overview
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 Transducers
which use special HAWK developed software where both units pulse & receive each others 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.
HAWK’s 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 & build-up off the face of the diaphragm.
