WATCH OUT FOR THE ENVIRONMENT
Metal Detectors are sensitive
instruments that can be called upon to work most harshly in outdoor logging
mills exposed to snow, ice and rain. The
equipment undergoes extreme expansion and contraction which over time opens up
joining surfaces, allowing possible ingress of water which in the case of Metal
Detectors is a major threat to sensitivity.
Surprisingly the operating
environment in a food processing factory can be just as harsh, for example in
meat processing plants. Here below zero
temperature operation is compounded by the need to wash down equipment from
time to time with high pressure steam and water jets that hit the Detector head
at pressures well over 5 bar seeking out any leaky routes to vulnerable parts.
It is essential when buying a Metal
Detector to keep this in mind particularly if high pressure wash down is
something it might have to withstand.
Things to look for :
·
All electronics and control circuits are
enclosed inside a stainless steel cabinet that meets Internationally recognised
leak proof standards such as IP67K
·
Conveyor belt bearings are sealed again to International
standards such as IP67K
·
Drive roller and drive motor are integral units
with the motor contained within and secured from the outside by sealed
bearings.
Cassel design Metal Detectors for
the very worst of environments outdoors and in plant. Most importantly the Sharknet facility now
allows the operation of units to be checked quickly and remotely following wash
down and after other similarly threatening environmental exposures.
