4.7 Mounting
SITRANS LC300
12 Operating Instructions, 05/2021, A5E47904073-AA
• Materials of construction are chosen based on their chemical compatibility (or inertness)
for general purposes. For exposure to specific environments, check with chemical
compatibility charts before installing.
• The user is responsible for the selection of bolting and gasket materials which will fall
within the limits of the flange and its intended use, and which are suitable for the service
conditions.
• Refer to the device nameplate for approval information.
• This product is susceptible to electrostatic shock. Follow proper grounding procedures.
• Before inserting the instrument into its mounting connection, check to ensure the threads
are matching to avoid damaging them.
• Cable entry devices and closing elements of unused apertures must meet a temperature
range from min. -40 to 10 K above max. ambient temperature.
Pressure applications
• Never attempt to loosen, remove or disassemble process connection or instrument
housing while vessel contents under pressure.
• Improper installation may result in loss of process pressure.
• For pressure applications, use PTFE tape or other appropriate thread sealing compound
and tighten the process connection beyond hand-tight.
• LC300 units are pressure tested, meeting or exceeding the requirements of the ASME
Boiler and Pressure Vessel Code and the European Pressure Equipment Directive.
Rope tensile strength
• Do not exceed the tensile strength of the rope at 1900 kg/4188 lbs.
• Always confirm that the load carrying capability of the silo/tank roof is sufficient to
withstand the actual force on the rope conditions, especially where the force will be, or
could be, as great as 1900/4188 lbs. A rope probe with a PFA jacket reduces the amount
of possible product buildup on the probe as well as the tensile force on the rope.
