All industries which need

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
The E-Z Tec Metal Detector uses a
balanced three–coil arrangement
wound around the aperture to sense
metal moving through it. The center
(oscillator) coil emits an electromagnetic field throughout the space within
the metal detector housing. Two
receiver coils (placed equidistant on
either side of the oscillator coil) are
connected in series so that the energy
coupled from the oscillator coil to
either of the receiver coils exactly
cancels the energy coupled to the other
receiver coil; the net output of this pair
is essentially zero. Metal passing
through this set of coils creates an
imbalance which, if the signal’s
amplitude is great enough, will result
in a detection.
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-
SENSITIVITY
The sensitivity of a metal detector is
usually defined as the diameter of the
smallest sphere which is always detected.
Many factors influence the sensitivity
that can be attained. These include:
product characteristics, type and shape of
metal to be detected, aperture dimensions, and the position of the metal
particle within the aperture. Actual
production line sensitivities can be
estimated more accurately when installation conditions and the customer’s
product are considered.
FEATURES
• Stainless Steel Design – The
oscillator and receiving coils are
wound on a rigid frame and
encapsulated in a stainless steel shell
(USDA/FDA and CSA approved).
• NEMA 4X Controls – The controls are
housed in a water–tight, dust–tight

ELECTRONICS
The E-Z Tec DSP Metal Detector’s
electronics have been consolidated and
placed in a NEMA 4X enclosure that can be
an integral part of the metal detector or
mounted up to 100–feet from the coils. Only
four circuit boards are used for improved
function and reliability.
The compact cabinet design allows for
shorter conveyor lengths and for installation
in those areas where space is a premium.

The E-Z Tec Analog Control utilizes a
unique combination of digital circuitry
and solid state amplifiers to process the
received signal. A crystal oscillator
provides a stable reference and drift free
electronics and provides the user with
manual selection of either WIDE ZONE
detection or NARROW ZONE detection.
• Wide Zone detection should only be
used where the incidence of static
discharge from product is contained
or antistatic pipes are used. Static
electricity is a unipolar discharge.
The polarity will either be positive or
negative causing a disturbance on at
least one of the two receiver coils. If
the disturbance is large enough a
false detection could occur.
• Narrow Zone detection will almost
eliminate false detections caused by
static electricity. Narrow Zone
requires each receiver coil to be
disturbed within a given time period,
and if only one coil is affected a
detection will not take place.
• The LED display will provide a visual
indication of the strength of the
detection signal in relation to the
metal size, and is also used to
monitor the phasing–out procedure
used for products that cause false
detection due to the presence of
moisture, salts or additives.
• Sensitivity control allows adjustment
of the detection threshold for
minimum and maximum metal
sensitivities.

directly control up to 99 metal detectors. So with MPCTerm, there is no
limit to the number of metal detectors
that can be monitored from a centralized location. And since the system
uses standard phone lines, MPCTerm
gives you worldwide connectibility for
remote monitoring and control.
• Remote connection can be initiated by
master or slave.
Real–time diagnostic functions have
been added to the E-Z Tec IV and V
MPC Metal Detector as well as to
MPCTerm. You can view on your
computer an oscilloscopic trace of a
signal from any networked E-Z Tec IV
or V MPC detector. This, along with the
enhanced remote operation capability,
means that operational problems of a
metal detector anywhere in the world
can be debugged by your central support
group or by the Eriez metal detector
experts in Erie, Pennsylvania, USA.
