Not all mills are designed alike and not all mills are constructed to accommodate a metal detector where it is needed. The TWA‑2000‑HD, with MP-4 Digital Technology, will meet expectations in demanding installations and consistently provide top performance in areas where other metal detectors have failed.

Hardwood mills face unique challenges when scanning dense woods such as red oak. MDI's TWA-2000-HD Metal Detectors operate at maximum sensitivity even when the largest hardwood logs are being processed.

Experienced sales staff and engineers are ready to design the perfect system for your application.



Virtually Eliminates Environmental Interference

In today’s mills, environmental interference, such as variable frequency drives, radio interference, and AC noise creates a big problem for many metal detecting systems. This may result in false tripping which will force you to lower your sensitivity and drastically reduce your metal detector performance. Our systems are designed to help filter out these effects.


Best Metal Free Zone

A metal free zone is the area in which a metal detector can operate efficiently without any interference. Some metal detector manufacturers will sacrifice sensitivity in order to operate in shorter metal free zones. MDI will quote the shortest metal free zone possible and still achieve the sensitivity your application requires.


Greatly Reduces Product Effect for Peak Performance

Any product, such as logs, that may have high levels of minerals or moisture with conductive properties will generate a response when passing through the metal detector. Our system extracts specific information from this response and applies sophisticated algorithms to classify it. Therefore, we can selectively reduce product effect and amplify desirable responses, giving you the best sensitivity for your metal detector with less or no false tripping.

Customizable MP-4 Microcontroller

The MP-4 Microcontroller offers optional settings that allow you to customize your metal detector for various applications. With digital technology you have the processing power to achieve higher performance with greater stability and better sensitivity. 


Digital Technology

Digital technology easily outperforms analog technology. In today’s world, digital technology plays a major part in modern electronics, such as computers, cell phones, and HI-Definition TVs. The processing power of a digital system greatly enhances performance and achieves powerful results. Software engineering has maximized the abilities of our digital technology to specifically accommodate the requirements of your application.
