Applications
A
metal detector bridge is used to detect and protect the size
reduction and production systems from damage and
destruction.
This can be caused by metal contamination that could be found in
the feed material.
Electronic
metal bridges are normally situated on the conveyor feed belt in
the size reduction system. ( i.e. granulator in-feed ).
All various
types of metals such as stainless steel, or copper are detectable.
These types of metal cannot be identified through magnet detection
but only through inductive detection.
The electronic detector can be used for all metals that are
electrically inductive.
Design
The
inner ( sender ) detection coil produces a high frequency
electro-magnetic field which penetrates the feeding material. This
sender coil emits 2 identical current fields which are transmitted
to the receiver coil
( E1 and E2 ).
|
Any
metallic contamination passing through this field alters the
energy field. The detected unbalance in the field is analysed and
converted into a switching impulse.
The main characteristics of
double layered detection coils
-
detects all types of metals, i.e. aluminium,
copper, brass, lead, stainless steel, etc.
- utmost sensitivity
-
self
monitor system: all necessary functions
are constantly monitored. The system is
activate through a blinking light and
relay
switch in the event of a systems fault
- quick
and easy sensitivity adjustment of
metal detection with dial to include vibration
and fault sensor. |
