Omega Piezo Technologies, Inc. is manufacturing the first effective damage reduction system for both tub and horizontal wood grinders (issued and pending patents). The Damage Alert System senses vibrations from unwanted metal objects that enter the wood grinder and reduces severe damage by shutting the grinder down and/or reversing the material feed system. The system will significantly reduce costly repair bills and down-time. System sensitivity can be adjusted to allow pass through objects and reduce nuisance shut downs.

The Damage Alert System is quickly and easily installed by using a magnetic clamping mechanism. The piezoelectric transducers are typically attached to the back side of the anvil and the mill bearing housing. The control box is attached to the grinder using four permanent magnets, in any convenient and accessible location. The transducers are connected to the electronics box via a coaxial cable and housed in corrugated tubing. All mounting hardware, cabling and connectors necessary for normal installation are provided. The company will also work with clients to engineer custom installation and system designs.

Once installed, the sensitivity of the Damage Alert System is manually adjusted using the red and green LED indicators. As debris is moved through the machine, the sensitivity level is fine-tuned to detect damaging debris of a prescribed size; the system is then set to the “ARM” mode for continuous operation and protection.

In the “ARM” mode, any pulses which are intense enough to illuminate the red section of the bar graph display, however briefly, will trip the system relay, instantly powering down the grinder or reversing the in-feed. The tripped condition is indicated with the steady illumination of the LED bar at the top of the display. If the grinder shuts down, the relay remains tripped, and the top LED remains illuminated until the obstruction is removed and the system is reset. The system is designed as a turn-key operational unit. Two separate sensor heads can be used, depending on application, machine size and design, and desired level of production.
