I.2 Options
I.2.1 Air Purge
The air purge option, Part No. KU-2A (Figure 2),
allows the interior of the KU-2 to be pressurized
with air (or an inert gas) when the instrument is
to be used in a hazardous environment. A built-
in pressure switch turns the instrument off when
the pressure drops below 2.0 PSI (falling). The
switch comes on at 10.0 PSI (rising).
Connect a regulated clean air (or inert gas) sup-
ply which is non-corrosive to brass to the fitting
shown in Figure 2. Adjust the pressure to ap-
proximately 25 PSI.
Note: The pressure switch range is 0-40 PSI.
DO NOT CONNECT PRESSURE HIGHER
THAN 40 PSI TO THE SWITCH!
I.2.2 Optinal Paste Spindle
The paste spindle, Part No. KU1-75Y (Figure 3), is a special
spindle; it is not included in a standard shipment/order. The
design consists of offset rod-type vanes, approximately 2 mm
diameter x 19 mm long. This spindle is suitable for use with
high consistency materials such as roller mill pastes. Do not
use this spindle to report normal Krebs Unit measurements
or centipoise. Record the grams value shown in the digital
display and note that the paste spindle was used to make the
viscosity measurement.
