Reliability levels up with vibrating switches January 1st 2009 The machine used to pack fill
sachets of Batchelors Cup a
Soup at Premier Foods' site in
Ashford, Kent, processes 160
units a minute. The hoppers
feeding the machine
incorporate a small rotating
agitator to ensure consistent
product flow and mix as the
sachets are filled. Previous
switches had reliability
problems, particularly when
products were changed over.
To help remedy the
situation, vibrating fork
devices have been supplied
with remote electronics
housings and quick release,
hygienic fittings to enable fast
removal and clean down
between product changes. The
application uses Vegawave
level switches from Vega.
Vibrating level switches
combine mechanical
detection – using the
damping of a vibrating
element – with the reliability
of solid-state electronics. Selfchecking
is built in, electronic
monitoring of the vibration
frequency means that any
damage, very high build-up
or device failure makes the
switch an inherently safe
device. More articles from Vega Controls Ltd: |
