Hawk Measurement Gladiator acoustic switch series transducers

Tuesday, 02 November, 2010 | Supplied by: Hawk Measurement Systems Pty Ltd



The Gladiator acoustic switch series with non-contact, self-cleaning technology can be used for blocked-chute detection.

The switch uses acoustic wave technology in a new sender/receiver form for blocked-chute detection, point level detection and anti-collision for heavy machinery. The Gladiator amplifier powers two AW transducers, which use software in which 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 either together or independently to detect pulse interference, allowing twice the application security. The acoustic wave transducers are self-cleaning and do not require contact with the product. The power of each pulse (pressure wave) blows the water, moisture and build-up off the face of the diaphragm. The switch requires a simple 1 min set-up and allows for remote test function. Communication options include GosHawk, Modbus, HART, Profibus DP and DeviceNet. The acoustic switch is designed for continuous operation in dusty, wet environments where other technologies fail.

The acoustic wave transducers are used for blocked-chute detection in wet or dry environments, wet screen blocked-chute detection truck/machine detection and sewage sludge handling.
