Installation
Mounting
Notes:
Installation shall be performed by qualified personnel and in accordance with local
governing regulations.
Do not bend, shorten or extend the tines.
Position the tines using a 50 mm open-end wrench when installing the process
connection (do not turn the housing). When side mounting SITRANS LVS100/200,
position the tines vertically, with the tine orientation marking facing up or down.
In pressure applications, use PTFE tape or other appropriate sealant to seal
tapered threaded connections.
After mounting, ensure the cable entries point downward to prevent water entering
the housing.
For the SITRANS LVS100/200 extended model, the torque due to material loading at
the mounting point may not exceed 250 Nm.
Mounting torque for the 1½" thread connection may not exceed 80 Nm.
WARNINGS:
LVS100 and LVS200:
• This product is designated as a Pressure Accessory per Directive
97 / 23 / EC and is not intended for use as a safety device.
• Improper installation may result in loss of process pressure.
• To install devices in hazardous locations, observe all valid installation
regulations.
• For Dust Ex installations: Before opening the device lid, ensure there
are no deposits present.
• Do not remove lid while circuits are live.
• Install the SITRANS LVS100/200 so mechanical friction or impact does
not cause sparks between the aluminium enclosure and steel vessel.
LVS200:
• Installation in Zone 0 (electronics: NAMUR): The intrinsic safe supply
circuit must have galvanic isolation to a non- intrinsically safe area.
Otherwise, provide protection for the device against lightning strikes
(see EN 60079-14).
• Power supply (electronics: NAMUR): Intrinsically safe protection is
only valid when connected to a certified intrinsically safe power
supply.
• For the LVS Pipe extended and cable extended models with Namur
electronics for gas hazardous approvals: When mounting the units on a
vessel lid that separates Zone 0 (Cat. 1G) from Zone 1 (Cat 2G), the units
have no safe separation between Zone 0 and Zone 1. Gas can pass
from Zone 0 through the unit to Zone 1.
