PRODUCT DESCRIPTION
The Jerguson model SAS-16 is a snap action magnetic level switch and has been designed to operate as
a point level switch for magnetic liquid level gauges. Please read this manual in its entirety before
installing the switch. Switch housing, nipple, and enclosure (when applicable) are constructed of 6061 T6
aluminum, designated by # = null, or 316SS designated by # = T.
All installation steps should be performed by a qualified technician and should be performed in accordance
with all applicable national and local codes.
OPERATION
The normal state of the SAS-16 is when the magnetic float is below the centerline/activation level of the
switch. In this normal state, the "A" leads are N/O and the "B" leads are N/C. When the float rises above
the activation level, the switch changes states, and persists until the float passes the activation level once
more.
INSTALLATION
To field mount the SAS-16 switch, simply tighten the provided hose clamps around both ears of the switch
assembly & the Magnicator chamber. Be sure to install the switch in the upright position, with "T" or "TOP"
facing up (denoted on the ear). Also, hose clamps will have to be fed behind any indicator or accessories,
taking care not to unnecessarily alter their positions.
Additional switch installation considerations:
1) Switch location should not be beyond either the travel range of the float, or the outer-most
process connections.
2) Switch orientation (left, right, or back side, etc.) should be within the active magnetic field.
Note label restrictions of active magnetic field on flash-proof designs.
3) Consult factory regarding Specific Gravity (SG) prior to mounting multiple switches at the
same locations.
When supplied with flying leads, an approved sealing fitting must be within 12mm (.47”) of enclosure. All
sealing fittings must be certified with appropriate ratings for the area.
For additional information refer to the appropriate control and installation drawing.
