The E-Z Tec® Metal Detec-

tor is an extremely sensitive

instrument used to detect the

presence of ferrous and

nonferrous metals.

All industries which need

product purity need metal

detectors. The list of examples

is almost endless, and includes

food, textile, rubber, plastic,

wood products, chemical,

cosmetic, pharmaceutical and

many other industries.

Besides the obvious benefit

of product purity, the metal

detector will also protect

downstream equipment from

damage caused by metal in the

product stream.

Metal can enter the

production process with the

raw material or can get into

the product due to wear or

failure of processing equip-

ment components. Detecting

pieces of broken machinery

can help resolve equipment

problems before major damage

occurs. Thus, equipment

downtime is reduced and

productivity is increased.

PRINCIPLE OF OPERATIONThe E-Z Tec® Metal Detector uses abalanced three–coil arrangementwound around the aperture to sensemetal moving through it. The center(oscillator) coil emits an electromag-netic field throughout the space withinthe metal detector housing. Tworeceiver coils (placed equidistant oneither side of the oscillator coil) areconnected in series so that the energycoupled from the oscillator coil toeither of the receiver coils exactlycancels the energy coupled to the otherreceiver coil; the net output of this pairis essentially zero. Metal passingthrough this set of coils creates animbalance which, if the signal’samplitude is great enough, will resultin a detection.

SENSITIVITYThe sensitivity of a metal detector isusually defined as the diameter of thesmallest sphere which is always detected.Many factors influence the sensitivitythat can be attained. These include:product characteristics, type and shape ofmetal to be detected, aperture dimen-sions, and the position of the metalparticle within the aperture. Actualproduction line sensitivities can beestimated more accurately when installa-tion conditions and the customer’sproduct are considered.

FEATURES• Stainless Steel Design – The

oscillator and receiving coils arewound on a rigid frame andencapsulated in a stainless steel shell(USDA/FDA and CSA approved).

• NEMA 4X Controls – The controls arehoused in a water–tight, dust–tightand corrosion resistant stainless steelenclosure. Other NEMA ratings areavailable upon request.

E-Z Tec DSP Control

Eriez’ state–of–the–art Digital ControlSystem provides a user–friendlyinterface through a menu–driven digitalhierarchy. The digital screen offersalphanumeric displays of all presetfunctions or reject occurrences as theytake place and also records the date andtime of product changes.

Digital processing and controls on allE-Z Tec DSP Metal Detectors allowfast product changes. The active(present) product can be changed viathe Touch–Screen Interface or remotelythrough RS-485 computer interfaceconnections.

50 different product selections can bestored with each product selectiondefining such parameters as sensitivity,gain, phase, product description andrelay states. Unauthorized changes areeliminated by a four level security code.Data memory retention preventsmemory loss. The control providesuser–specified self–checking andperiodic calibration procedures.

The report menu displays report number,product, date, time and magnitude of thereject signal. The internal memoryholds full details of the last 100 rejectsfor visual review, counting up to 10,000rejects. Reports may be uploaded to acomputer via the RS-485 interface port.An unlimited record of reject reports canbe stored on the computer.

• Bar Graph will provide a visualindication of the strength of thedetection signal in relation to themetal size, and is also used to monitorthe phasing–out procedure forproducts.

• Threshold adjustment allows forsetting of the detection threshold forminimum and maximum metalsensitivities.

• Phase adjustment provides theuser with the capability to adjustthe metal detector to minimizeproduct effect and the ability topeak a response to a particularmetal.

• Shift Register stores multipledetections for precise rejection ofmetal. A tachometer input isprovided for variable productspeeds.

• Travel Time is an adjustmentcontrolling delay of the detectionsignal output. This will allowtime for the detected contaminantto be positioned at thedownstream reject device (suchas, air blow off, pusher arm, flipgate, etc.). It can be set from 0-60seconds with a 0.05 secondresolution.

• Reject Time is a variableadjustment for extending thereject output signal. This featureallows the user to adjust the rejectoutput time from 0.05 to 60seconds.

• Output Relays include twoindividually programmable relays,one with two form “C” contactsand the other with one form “C”contact.

E-Z Tec Analog Control (E-Z Tec V Only)

• The LED display will provide a visualindication of the strength of thedetection signal in relation to themetal size, and is also used tomonitor the phasing–out procedureused for products that cause falsedetection due to the presence ofmoisture, salts or additives.

• Sensitivity control allows adjustmentof the detection threshold forminimum and maximum metalsensitivities.

• Phase provides the user with controlfor adjusting the metal detector forproduct effect.

• Travel Time is an adjustment for delayof the detection signal output. Thiswill allow time for the detectedcontaminant to be positioned at thedownstream reject device (such as, airblow off, pusher bar, flip gate, etc.).

• Reject Time is a variable adjustmentfor extending the reject output signal.This feature allows the user to adjustthe reject output time from 0 to 10seconds.

The E-Z Tec Analog Control utilizes aunique combination of digital circuitryand solid state amplifiers to process thereceived signal. A crystal oscillatorprovides a stable reference and drift freeelectronics and provides the user withmanual selection of either WIDE ZONEdetection or NARROW ZONE detection.

• Wide Zone detection should only beused where the incidence of staticdischarge from product is containedor antistatic pipes are used. Staticelectricity is a unipolar discharge.The polarity will either be positive ornegative causing a disturbance on atleast one of the two receiver coils. Ifthe disturbance is large enough afalse detection could occur.

• Narrow Zone detection will almosteliminate false detections caused bystatic electricity. Narrow Zonerequires each receiver coil to bedisturbed within a given time period,and if only one coil is affected adetection will not take place.

• Mechanical Relays include twoindividual fused (5 amp) relays withindependent control for variousoutput functions (reject devices,alarms, PLC’s, etc.).

Eriez’ has made its metal detectioncomputer interface, MPCTerm, morepowerful. It’s packed with excitingnew features.

MPCTerm makes remote access tometal detectors possible through asimple modem and phone line connec-tion. One or more “master” computerscan connect with an unlimited numberof “slave” computers. Each slave can

directly control up to 99 metal detec-tors. So with MPCTerm, there is nolimit to the number of metal detectorsthat can be monitored from a central-ized location. And since the systemuses standard phone lines, MPCTermgives you worldwide connectibility forremote monitoring and control.

Real–time diagnostic functions havebeen added to the E-Z Tec IV and VMPC Metal Detector as well as toMPCTerm. You can view on yourcomputer an oscilloscopic trace of asignal from any networked E-Z Tec IVor V MPC detector. This, along with theenhanced remote operation capability,means that operational problems of ametal detector anywhere in the worldcan be debugged by your central supportgroup or by the Eriez metal detectorexperts in Erie, Pennsylvania, USA.
