Precautions:
•
Avoid proximity to high voltage or current wiring, high voltage or current contacts,
and to variable frequency motor speed controllers.
•
Avoid interference to the sound path from obstructions or from the fill path
The sound path should be:
•
perpendicular to the
monitored surface
•
clear of rough walls,
seams, rungs, or
other obstructions.
•
clear of the fill path
Mounting Instructions
Note:
•
Ideally, mount SITRANS Probe LU so that the face of the transducer is at least 300
mm (1 ft) above the highest anticipated level.
•
More than one Probe LU can be installed in a vessel. However, best practice would
be to place the two units as far apart as possible to avoid interference.
SITRANS Probe LU is available in three thread types: 2" NPT, 2" BSP , or PF2/G.
1.
Before inserting SITRANS Probe LU into its mounting connection, ensure that the
threads are of the same type to avoid damaging them.
2.
Simply screw SITRANS Probe LU into the process connection and hand tighten or
using a strap wrench to seat gasket if required (1/4 turn past hand tight is
recommended).
