Form 924 (05.18) ©SOR Inc.
Conduit must be installed between the sensor base and the electronics housing to provide
a raceway for sensor extension cables. (See
).
If the sensor is a solid rod it may be cut or bent for clearance or placement. Use a 3-inch radius
should a bend be required. It is permissible to increase the sensor length by welding a length of
identical rod to the supplied sensor. Re-calibration is required if the probe length is changed.
Installation
Standard Confi guration
is a 3/4” NPT(M) pipe nipple that threads into a 3/4” NPT(F) vessel
nozzle or half coupling. Allow a 4-inch turn radius. (See
and
). Open tanks, vats,
sumps or basins may require a locally-made bracket mount similar to that shown in
.
Optional Confi guration
is a raised face or flat face ANSI flange. See Form 1100 for selection.
(See
and
).
Orientation
The control can be mounted in any position. Placement and orientation of the
sensor in a vessel is usually determined by available nozzles. The sensor should be away
from fill points to avoid false trips. The insulator bushing on the sensor should protrude
a minimum of 1” from the inner wall of the vessel. The sensor must not touch any metal,
nor should conductive process build-up be allowed to bridge between the sensor and a
grounded metal tank wall.
This product must be installed with an explosion proof breather vent
per Agency requirements and the National Electrical Code-Article 501,
Section F, paragraph 3.
