Watch a sophisticated 2-wire system to monitor

Pull Cord & Belt
Sway Switches are installed along the length of conveyor
to provide safety against malfunctioning.
Modern complex bulk
material conveying systems contain a large number of
belts having considerable lengths, involving hundreds
of safety switches. Checking out the actuated switch
for rectifying and putting the system back into operation,
therefore, becomes a long drawn out process resulting
in huge production loss.
While some relief was
provided by indicating flags or lamps fitted on the
individual switches, it was imperative to provide an
arrangement to enable the operator in the remote control
room to know immediately the location of the 'operated'switch.
So far, this was being
achieved by providing the 'Diode Plates' inside the
switches to identify the location of the'operated' switch
by audio-visual display in the control room with suitable
control circuitry.
The biggest disadvantage
of this system was the necessity to lay multi-core cable
along the conveyor. More the number of switches, more
was the number of diodes per switch & consequently
more number of cores in the cable. The cost of such
multi-core cable matched or even exceeded that of the
safety switches themselves.
Jayashree has
now introduced “BELT WATCH “- the sophisticated monitoring
system that is simple, cost effective and most importantly-highly
reliable.
