Fortress Technology began in 1996; believing that through superior product design and engineering, the production of higher quality equipment with better sensitivities could be achieved. The phenomenal market response to our Fortress Phantom line of metal detectors validated that belief and the philosophy on which it is based; simple operation, outstanding reliability, and exceptional performance.

Fortress metal detectors have always been engineered with a Never Obsolete Commitment. Our latest technology can quickly and economically be field installed in a detector built over 20 years ago. Fortress metal detectors will always be supported with parts, software upgrades and a global service team for the life of the detector, so you stay up to date with food safety initiatives without having to purchase a new detector.

Fortress Technology is the only Metal Detector Manufacturer that, since our inception, custom manufactures our equipment and software, to suit a customers’ needs, applications and specifications to ensure optimal metal detection with a high ROI. We are renowned in the industry for superior performance and sustainability, our equipment is used widely in various industries all over the world. A global enterprise, we have manufacturing offices in Canada, the UK, and Brazil serving our worldwide distributors.

We have absolute confidence in our products; if they do not perform as anticipated, we will work with you to rectify the situation or provide a full refund.

金屬種類與檢測靈敏度

現實中金屬的種類繁多，對于不同種類的金屬，金檢機的檢測靈 敏度是不相同的。據檢測難易程度和金檢機原理，我們傾向于將所有金 屬分類兩大類，磁性金屬和非磁性金屬，磁性金屬函括鐵、鈷、鎳元素 為代表的合金材質金屬，其它的都為非磁性金屬，由于函括范圍較大， 如銅，鋁，合金，不銹鋼 等等。所以通常采用信號的銅(非鐵)和最 弱的不銹鋼(304/316)做為檢測標準，固通常需要檢測三種類型： 

鐵金屬(Fe):     可以很容易被磁鐵吸引的金屬，例如純鐵。這類金屬通常是在食品制 作中見的異物，而且最容易被金屬檢測機檢測，所以其靈敏度是。 

非鐵金屬(Non-Fe):  高導電的非磁性金屬，例如銅，鋁，金，銀，黃銅等）。 當被檢測的產品是屬于干貨時，其靈敏度會接近可被檢出的鐵金屬的尺寸。 如果產品是屬于濕貨時，其靈敏 度會低于鐵金屬， 可檢出的非鐵金屬尺寸會比鐵金屬的尺寸大至少 50%。 

不銹鋼（SUS）:  300 系列不銹鋼，例如 304，316。根據金屬檢測的定義及技術，而且不銹 鋼擁有較低的導電性和磁導率，所以不銹鋼的靈敏度是所有常見的金屬中的。 當被檢測的產品是屬于干貨時，不銹鋼球的尺寸需要比鐵金屬的尺寸大 50%，才可產生相同的信號。 但當產品是屬于濕貨時，不銹鋼球的尺寸需要比鐵金屬的尺寸大 100 至 200%，才可產生相同的信號
