For many years
ABM Metal Detectors has been designing various types and sizes of
metal detecting systems for applications ranging from the food manufacturing
up to systems that require special DIP requirements used in the
defence industries or other hazardous areas. Our metal detector
aperture sizes can range from a small 100mm wide x 70mm high, up
to a massive 2400mm wide x 1200mm high for the special application
with excellent sensitivity and product compensation control.
All models
are high performance metal detectors suitable for detecting ferrous
and non-ferrous metallic contamination in a wide range of non-metallic
products. These units consist of a detector head, an electronic
module with power supply and relay output with full reject timing
controls. A selected range of Series 4B detectors can as an option
be constructed with removable end plate design or remote mounted
electronic controls up to 10 metres away without any operating problems.
Also available
is a range of vertical fall or drop through metal detectors which
can also be used for pipeline applications. The VF range of detectors
have an extremely low metal free zone of approximately 40mm each
side of the detector head and also as a standard, have remote mounted
controls up to 10 metres away for ease of operation. These drop
through metal detectors are commonly used on form fill and seal
machines mounted just above the forming tube or other applications
for gravity fed, free flowing powders, pipeline, liquid or granular
materials. Each model in the range operates with analog main controls
with digital pulse phase modulation and phase discriminating signal
demodulation network coupled to a dual gated detection system. The
dual gated detection system is a feature that eliminates early tripping
when metal contaminants are being conveyed through the detector
head. Detection actually occurs when the metal contaminants just
pass through the centre of the detector head. This system allows
excellent product compensation and sensitivity, also minimises the
amount of good product reject.
