The Tectron Tramp Metal detectors are designed to detect ferrous and
non-ferrous metal in the presence of materials transported on
conveyor sections. Tectron use a unique ‘Pulsed Eddy Current’
technique for optimum metal detection sensitivity and noise
rejection. The ‘Pulsed Eddy Current’ technique has the major benefit
of being able to detect tramp metal in the presence of magnetic and
conductive materials. The system will also tolerate changes in
product properties without tripping. The system is comprised of a
single transmission coil mounted above the conveyor belt with a
single or dual receiver coil mounted below the conveyor belt. An
electric pulse energizes the transmission coil at regular spaced
intervals. As the field setup decays a strong electromagnetic field
is created. This field
will induce energy into any metal passing through the detector. The
receiving coil/antenna will detect this and trigger a ‘Tramp metal’
event. The system electronics have also been designed to distinguish
electrical noise from a legitimate metal signal. Incoming noise
signals are blocked from downstream circuitry to reduce the chance
of false triggering/tripping depending on how the system is
configured. This is particularly important in areas where electrical
storms or radio interference signals are experienced.
