Code: 7ML5731/7ML5732/7ML5733/7ML5734
Product name: SITRANS LVS200

SITRANS LVS200 is a vibrating point level switch for high or low levels of bulk solids

  Benefits
• High resistance to mechanical forces
• Strong vibration resistance to high bulk material loads
• Rotatable enclosure
• Suitable for low density material: standard version, 20 g/l
(1.3 lb/ft3); liquid/solid interface version, 50 g/l (3 lb/ft3), and
low density option min. 5 g/l (0.3 lb/ft3)
• Customer desired extensions up to 20000 mm (787")
• Optional detection of solids within liquid
• Durable short fork option with 165 mm (6.5") insertion length
Application
The standard LVS200 detects high, low or demand levels of dry
bulk solids in bins, silos or hoppers. The liquid/solid interface
version can also detect settled solids within liquids or solids
within confined spaces such as feed pipes. It is designed to ignore
liquids in order to detect the interface between a solid and
a liquid.
A pipe extension version is available with either the standard or
liquid/solid interface electronics and fork, separated by a customer
supplied 1" pipe.
SITRANS LVS200 has an optional 4 to 20 mA output for monitoring
buildup on the fork to determine when preventative maintenance
should be performed in sticky applications.
The LVS200 has a compact design and can be top, side or angle
mounted. The vibrating fork design ensures the tines are kept
clean. The unique design of the fork and crystal assembly eliminates
false high level readings even if tines become damaged.
A signal from the electronic circuit excites a crystal in the probe
causing the fork to vibrate. If the fork is covered by material, the
change in vibration is detected by the electronic circuitry which
causes the relay to change state after a one second delay. When
the fork is free from material pressure, full vibration resumes and
the relay reverts to its normal condition.
• Key Applications: dry bulk solids in bins, silos, hoppers or settled
solids within liquids (interface version)
