SMI30 Series Intrinsically Safe Sensors
5
These new water-tight aper-
tures for SM30 Series sen-
sors may be used to size and
shape the effective beam or
to limit excess gain for avoid-
ing "burn-through" effects.
Apertures are sold as a kit,
which includes a thread-on
stainless steel housing, a flat
glass lens, two quad-ring
seals, and 3 round and 3 slot-
ted aperture disks.
The stainless steel aperture
housing functions equally
wellwithVALOX®andstain-
less steel sensor models. The
glass lens is useful for pro-
tecting the SM30's acrylic
lens against substances that
are hostile to acrylics, such
as concentrated acids and alkalis and industrial solvents.
Aperture sizes include the following.
Round: .06", .12", and .70" diameter
Slotted: .04", .10", and .20" wide
