Installation Instructions

Notes:
• There is no limit to the number of times the device can be rotated without damage.
• When mounting, orient the front or back of the device towards the closest wall. For
an illustration of a stillpipe application see
on page 18.
• Do not rotate the enclosure after programming and device configuration, otherwise
an error may occur, caused by a polarity shift of the transmit pulse.
1. Before inserting SITRANS LR200 into its mounting connection, check to ensure the
threads are matching, to avoid damaging them.
2. Simply screw SITRANS LR200 into the process connection, and hand tighten. For
pressure applications, it will be necessary to use PTFE tape (or other appropriate
thread sealing compound) and tighten the process connection beyond hand tight.
The maximum torque is 40 N·m (30 ft.lbs).
3. If you want to rotate the enclosure,
use a 2 mm Allen key to loosen the
set-screws that secure the locking
1)
ring .
4. Once the enclosure is in a suitable
position, tighten the set-screws.
1)
When the locking ring is secured, it prevents the enclosure rotating on the threaded con-
nection.
