Selecting the Best Metal Detector

Selecting the Best Metal Detector
2
INFORMATION

• Consumers expect consistent and high-quality
  products. Metal detection assists manufacturers
  in effectively ensuring product quality while
  staying within budget. When evaluating a metal
  detector, look for technical performance.
• One of the most important functions of a food and
  pharmaceutical manufacturer is brand protection
  in the marketplace. However, your investment in
  establishing a reputation for product quality
  could be wiped out by a single safety recall.
  Developing and maintaining an effective,
  verifiable inspection programmer is no longer an
  option for processors it was never an option in
  the first place.
• How can you protect your customers and brand
  while staying within your budget? Metal detection
  is an effective and reasonably priced solution.
  While price, delivery, and other commercial
  considerations are important, technical
  performance should be the primary consideration
  when deciding which metal detector to entrust
  with your brands reputation.

PRODUCT IMPACT

• When choosing a metal detector, consider the
  product effect. If your products are conductive
  (usually due to the presence of water, salt, or
  iron), they will affect the electromagnetic field
  of the metal detector, resulting in a false
  reject. In general, dry or neutral products do
  not have this effect. If product effect is a
  factor, choose the appropriate frequency to shift
  the product effect signal away from the
  contaminants signal. A single-frequency metal
  detector cannot accommodate much signal
  variation, making it unsuitable for inspecting a
  variety of product types or those that vary in
  temperature. For these applications, a metal
  detector with multiple frequencies is preferable.
  Multi-spectrum technology is used in the most
  sophisticated metal detectors on the market.
  Instead of relying on a single frequency, a
  spectrum of multiple frequencies works
  simultaneously to filter out product signals,
  which is a much more effective method than a
  single frequency and reduces the number of false
  alarms significantly.

ADVANTAGES OF AUTO-CALIBRATION AND AUTO-LEARNING

• The metal detector that successfully integrates
  into a plant quality control programmer has good
  sensitivity performance, is simple to set up and
  use, and has a low level of false rejects. Most
  metal detectors on the market today perform
  self-checks to ensure that the unit is balanced
  and operating properly. The auto-learn routine
  enables the user to acquire product
  characteristics in the unit so that the product
  can be inspected. An efficient auto-learn
  provides the highest sensitivity with the fewest
  false rejects and requires the fewest manual
  adjustments. This expedites the units production
  of a new product.

COMMUNICATION AND SENSITIVITY

• Metal detection sensitivity requirements are
  frequently determined by the operation. For
  example, if the primary function of a metal
  detector is to protect a critical piece of
  equipment, such as a sheeter or slicer, the goal
  would be to eliminate metal large enough to
  damage the equipment. A different level of
  sensitivity would be required in another part of
  the line to inspect a bulk flow of product.
  Furthermore, because final package inspection is
  typically the most demanding, a higher level of
  sensitivity would be required to protect your
  product before it reaches the market. For each
  inspection operation, your plants quality
  control group should set specific sensitivity
  targets for ferrous, nonferrous, and stainless
  steel contaminants (including the
  difficult-to-detect type 316). These targets
  should be communicated to the metal detector
  manufacturer so that the appropriate equipment
  can be selected for each application. Remember to
  be adaptable in order to achieve realistic and
  reachable goals within your budget.

CONSIDERATIONS FOR THE ENVIRONMENT

• Begin by assessing your inspection area. Is the
  weather wet or dry? What is the temperature
  range? It is critical to choose a metal detector
  that is appropriate for your operating
  environment. Water intrusion into the electrical
  components is one of the most common causes of
  metal detector failure. Is the wash-down regimen
  in the plant high or low pressure? Take note of
  the IP rating. An IP65 wash down rating indicates
  that the metal detector can withstand low
  pressure wash down with room temperature water
  an IP69K rating indicates that the metal detector
  can withstand sustained high temperature and
  pressure. However, keep in mind that these
  ratings are typically self-reported. The
  manufacturers industry reputation for the
  ability of its equipment to withstand wash down
  can be a good indicator.
• Is there anything caustic in the wash down? If
  this is the case, special consideration should be
  given to the specific alloy of stainless steel
  used for the metal detectors case. These caustic
  agents are more resistant to Type 316L. Is the
  metal detectors finish painted for dry
  environments? Placing a painted surface in the
  product stream may result in paint chips
  contaminating your products. Consider impact
  resistance as well. Plastic covers and membranes
  are prone to abrasion and impact penetration. A
  durable display screen and keyboard help to
  reduce downtime and part replacement costs.

CONSIDERATIONS FOR COMMUNICATION

• Will the metal detector be a stand-alone piece of
  equipment, or will it have to be integrated into
  the plants network to provide periodic data
  reporting for a statistical package? Is there
  ready-made software that can perform these
  functions on the unit? Is it Ethernet capable?
  Some manufacturers provide software packages that
  enable remote programming and diagnostics via
  laptop, including oscilloscope emulation via
  Bluetooth, without requiring the power supply
  cabinet to be opened.

EVENT MONITORING

• Equipment must keep up as food and pharmaceutical
  manufacturing regulations become more stringent.
  What are the internal requirements for metal
  detector event tracking? Is it necessary for all
  operators to use the same passwords? Should each
  user have a unique password that allows them to
  access only the levels that management deems
  appropriate for the individual? Each machine
  entry (e.g., product change, sensitivity change,
  reset) in this case can be traced back to a
  specific operator. Choose a metal detector that
  meets the access and event tracking requirements
  of these internal requirements.

AFTER-SALES SERVICE

• As with any equipment purchase, the buyer is
  entering into a long-term relationship that
  includes upfront application assistance,
  training, parts supply, and technical support.
  Choose a dependable supplier with whom you feel
  at ease and who provides ongoing assistance.
