1.6 OPTIONS AND
ACCESSORIES
1.6.1 Where can Liquid Level Switches be
Fitted?
Liquid level detection methods can be attached to
the 1 quart bowl and 2 & 5 gallon tanks.
1.6.2 Where can Remote Fill and Liquid Level
Switches be Fitted?
The smaller bowls, L73 and up, are all capable of
either remote fill or liquid level detection (but not
both at the same time!). The 2 quart and 2 & 5
gallon tanks only can have the liquid level switches
fitted.
1.6.3 How do Liquid Level Switches Work?
Liquid level switches are bipolar reed switches
which change state when the float rises and falls.
Liquid level switches are normally
connected to give an electrical signal when the float
falls (ie when the liquid level is too low). In critical
applications the logic could be reversed. Maximum
and minimum settings are possible too.
1.7 LARGE TANKS/RESERVOIRS
1.7.1 Which Units have Large Tanks/Reservoirs?
All units in basic 1/2” and above have optional
larger bowls/tanks.
Olympian Plus and Excelon 74 are limited
to 1 quart as standard. For 2 and 5 gallon capacity
use 15/17 Series, or the 10-028/-076 (2”)
lubricators.
1.8 APPLICATION SPECIFIC
UNITS
1.8.1 Do we Make Bearing Lubricators?
These are aerosol type lubricators. These
lubricators use air to get the oil to the point of
lubrication, however the tool or application is not
powered by the air. Although produced by Norgren,
systems for their application are designed and sold
by Engineering and General Lubrication Systems.
1.8.2 What is a Fixed Venturi (Bi-Directional)
Lubricator?
Standard Norgren lubricators use a flow sensor to
achieve constant oil density with varying flows. In
some applications high flow is more important than
constant density and a fixed venturi can be used
instead of a flow sensor. It may also be useful in
systems with rapid cycling. Consult Air Line for
more details.
1.9 OILS
1.9.1 What Oils are Recommended?
Recommended oils fall into 2 categories:-
1
Oils recommended for use with all Norgren
units (valves, cylinders, fittings and FRL’s).
2 Oils which can be used with Norgren
lubricators but not necessarily with other
Norgren equipment.
Refer to ALE-29-2 for recommended lubricants.
1.9.2 Can Non-Recommended Oils be Used?
Some oils can be tested for suitability, but Norgren
cannot be responsible for use of non-recommended
lubricants.
