Blocked Chute Protection Switches

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 and sewage sludge handling.

The Gladiator Amplifier powers two AW Transducers which use special Hawk developed software where both units pulse and receive each other's 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.

Hawk's Acoustic Wave Switches 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.

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

Primary Areas of Application:
Brewing, Cement, Chemical, Fertilizer, Food & Beverage, Glass, Mining & Metals, Packaging, Paper, Pharmaceutical, Plastics, Power Generation (coal fired), Refining, Sugar, Water & Wastewater, Sewage Sludge
