Electrical Installation
WARNING:
Do not connect the LSK to a high DC potential, which could damage
the sensor. The most suitable evaluation module is a type with a
sensing frequency > 00 Hz and input voltage < 5Vrms.

Mechanical Installation
Welding part
Please refer to “Accessories” data sheet. The welding part has an
engraved mark or hole. When the product has been mounted and
correctly tightened the gland or M plug will align with this mark.
Make sure that the gland/plug is pointing downwards to prevent fluids
from penetrating into the instrument.
Cautions
Use only the authorised special designed accessories.
The product warranty is void when installed with other adapters.
The sensor can be shortened.
Coated rods: Remove approx. 0 mm of the coating from the rod tip to
ensure a proper contact to the media.
Do not use teflon, paper or other gaskets.
The process connection must have electrical contact with the tank.
if not, a separate grounding cable must be installed.
If the tank is non-conductive an additional ground electrode must be
installed. This should have electrical connection to the LSK process
connection.
Make sure that the rod can not touch the tank wall even with the high-
est movement of the media.
When installed <00 mm from the tank wall the rod must be parallel
with the tank wall. For larger distances non-parallelity can be allowed.
After carefully insertion of the sensor into the welding part tighten the
union with a torque of:
LSKxx: 0...0 Nm.
LSKx5x: 0...30 Nm.
After Installation and Configuration
Check the leak tightness of the sleeve.
Check the tightness of glands or M plugs.
Check the tightness of the cover.
Check that the rod is not touching the tank wall.
