(لا يتفق الجميع على أنه كلما أنفقت أكثر، كان المنتج أفضل) ولكن هذا هو رأينا عندما يتعلق الأمر بهذا الموضوع، “عندما تنفق المزيد من الأموال على أجهزة الكشف عن الذهب، فإنك تحصل على ملفات بحث أفضل، والمزيد من الوظائف والخيارات مع أعلى كاشف جودة “. كل هذا يعني العثور على ذهب أكثر قيمة، واستخدام أفضل لوقتك. “
The examples and viewpoint With this segment offer mostly with America and do not represent a all over the world view of the subject. You could possibly enhance this area, examine The problem to the speak webpage, or make a new section, as acceptable. (June 2013) (Learn the way and when to eliminate this information)
بعد تحديد الإعدادات السابقة ، يمكن للمستخدم بدء عملية البحث ، وأثناء البحث ستتحرك الهوائيات يسارًا أو يمينًا اعتمادًا على الأهداف القريبة المحتملة ، وسيوجه مؤشر مرئي على الشاشة المستخدم لأنه يعرض شريط تقدم يسارًا أو يمينًا مع تدرج الألوان من الأخضر (الحد الأدنى) إلى الأحمر (القيمة القصوى) بناءً على الموضع المستهدف.
The simplest type of a metal detector includes an oscillator manufacturing an alternating recent that passes by way of a coil creating an alternating magnetic area. If a bit of electrically conductive metal is close to the coil, eddy currents will likely be induced (inductive sensor) from the metallic, and this generates a magnetic industry of its very own.
يعمل عن طريق بطارية ليثيوم بوليمر خارجية موجودة في صندوق بلاستيكي مصمم بشكل مميز لإمكانية نقل واستبدال أفضل ، ويمكن إعادة شحن البطارية وضمان فترة تشغيل طويلة.
The biggest technical modify in detectors was the development of a tunable induction technique. This method associated two coils that are electro-magnetically tuned. 1 coil acts being an RF transmitter, the other to be a receiver; in some cases these could be tuned to concerning three and 100 kHz. When metal is within their vicinity, a sign is detected owing to eddy currents induced inside the steel. What permitted detectors to discriminate among metals was The reality that every single steel has a different section reaction when subjected to alternating current; for a longer time waves (lower frequency) penetrate ground deeper, and choose for top-conductivity targets like silver, and copper; than shorter waves (higher frequency) which, whilst considerably less ground penetrating, decide on for small-conductivity targets like iron.
If An additional coil is used to evaluate the magnetic discipline (performing to be a magnetometer), the adjust in the magnetic discipline as a result of metallic item may be detected.
Lots of makers of such new products introduced their own personal Strategies to the industry. White's Electronics of Oregon began from the nineteen fifties by creating a machine known as the Oremaster Geiger Counter. A further chief in detector technology was Charles Garrett, جهاز كاشف المعادن والذهب who pioneered the BFO (conquer frequency oscillator) machine. Together with the creation and enhancement from the transistor while in the nineteen fifties and 1960s, metal جهاز كاشف معادن detector brands and designers made smaller sized, lighter devices with improved circuitry, functioning on tiny battery packs.
في حالة التنشيط ، يمكن ضبط قيمة الوقت الذي يحتاجه الجهاز لإيقاف تشغيل الشاشة (في حالة عدم الضغط على أي زر لفترة من الوقت) ، وهذا يضمن حفظ طاقة البطارية لفترة أطول استعمال.
Coil designers also experimented with out modern patterns. The first induction harmony coil method consisted of two similar coils placed on best of one another. Compass Electronics made a different design and style: two coils within a D form, mounted again-to-back again to sort a circle. The process was commonly Utilized in the seventies, and equally concentric and double D type (or widescan since they turned recognized) experienced their lovers. An additional improvement was the creation of detectors which could terminate out the influence of mineralization in the bottom.

Each time a metallic contaminant is launched in the product or service an unequal disturbance is established. That results in an exceedingly compact Digital sign. Following ideal amplification a mechanical system mounted to the conveyor process is signaled to get rid of the contaminated products from the production line. This method is totally automatic and will allow producing to function uninterrupted.
