Since the market introduction of the current 652 series, WAGNER metal detectors have been used successfully
all over the world to protect mills, crushers, cutters and other valuable system parts.
They work around the clock and under many extreme climate conditions, for example in cement, gravel and woodcutting
factories, in glass and paper recycling plants and also in coal power stations.
In general, the user-friendliness, reliability and disturbance-resistant, robust housing are given
positive reviews by our customers. The transmitter and receiver coils are sealed with special filler
material together with the shielding steel sheet metal housing. For this reason, our devices are very
resistant to mechanical and thermal loads.
If none of our standard devices can be installed because of especially difficult installation conditions,
we can manufacture custom designs. The control electronics can be mounted up to 50 m from the sensor at
a location that can be easily accessed.
No special knowledge is required for commissioning. Our operating instructions provide a detailed
explanation of what needs to be done. The display sensitivity setting for all devices is continually
variable over a wide range. As soon as a magnetic or non-magnetic metal item with sufficient size
passes through the search area, it is detected and a potential-free relay contact is switched. This
signal can be output as a pulse with an adjustable length or as a continuous signal. The continuous
signal can be acknowledged by the operator using the control electronics after removing the metal item.
Tandem sensor type 653/2
Our most often sold sensor type is available for belt widths from 200 mm to 3000 mm. It consists of
a sensor lower section, which is mounted below the belt, a distance frame and a sensor upper section,
which is placed above it. Subsequent installation in existing conveyor systems is normally possible
without problems because the sensor can be split into sections. The search sensitivity is evenly
distributed over the entire working area.

Tandem sensor light design type 653/2L
We have developed this light and compact but robust and disturbance-resistant sensor type especially
for the stone and earth industry. It can be used for belt widths from 300 mm to 1000 mm. The low
weight and compact dimensions make subsequent installation easier especially in difficult installation
conditions. This sensor type is perfectly suited for protecting crushers in gravel pits and quarries.

Special designs
Often, existing building and construction parts make the installation of standard devices more
difficult. We construct custom devices for these especially difficult areas of use. We can also
deliver metal detectors that correspond to ATEX regulations for use in areas where explosions could
occur. Our sales representatives will be happy to check your application on-site and provide detailed
advice.

Single plate sensor type 653/1
Single plate sensors are very good for monitoring shallow material depths because of the especially
high sensitivity near the sensor surface. Transmitter and receiver are integrated in one sensor housing
that is mounted directly under the conveyor belt on the conveyor frame. The metal housing provides very
good shielding against disturbances around the device. The standard device can be used for material
depths up to a maximum of 150 mm.

Single plate sensor light design 653/1L
This special type has greatly reduced housing dimensions as compared to the standard device so that
it can also be mounted in tight spaces. Here, a metal housing also provides protection from outside
influences and makes the device secure and robust. Because of the compact design, the search area is
so concentrated that even metal construction parts short distances away do not disturb the device.
For layer depths under 75 mm, this device is the perfect solution.

Vertical sensor type 653/4
Vertical sensors are manufactured with round or square openings. The inseparable measurement system encloses the conveyor track completely and therefore provides the highest search sensitivity with evenly distributed sensitivity. The area of use ranges from monitoring pneumatic conveyor systems and checking packages to inspecting tree trunks. Openings up to 1600 mm are possible.
Control electronics type 650/2
The extremely user-friendly designed control electronics can be used to control all shielded sensor types made by WAGNER. The desired display sensitivity adjustment is continuously variable over a wide range. The distance between the control electronics and sensor can be up to 50 meters. Disturbances are cancelled out using the most modern signal preparation techniques.
Signal lights and special accessories
We offer various combinations of blinking and signal lights as well as acoustic signal devices as accessories to optically display operational readiness and metal detection. Sandbag marking devices are used if the conveyor belt runs for different distances after metal is detected. They are mounted over the conveyor system after the metal detector and drop a sandbag on the conveyor material after metal has been detected.
