1.3 THE SI9005 CAN STAND
Due to the corrosive nature of the electrolytes used in enamel
rating the life of probe attachments can be very poor. With this in
mind, the SI9005 has been designed using nylon parts wherever
possible, whilst all metal parts are made from specially selected
stainless steels, heat treated where appropriate. The wiring of the
can stand is completely sealed against corrosion from electrolytes
which not only improves the life but ensures accuracy and reliability
of the readings taken.
Electrical contact is made with the can by three hardened knife
edges, one of which is wired separately to allow electrical contact
checking, and the two probes (one for rating and a shorter probe
for level checking) are supported on an adjustable arm and
telescopic column. This arrangement allows the probes to be lifted
and rotated to one side while the can is being inserted.
