Vibrating Level Switch

SITRANS LVS100 is a vibrating point level switch for bulk solids which detects high, low or demand levels of dry bulk solids in bins, silos or hoppers. The compact design can be top, side, or angle mounted.

The SITRANS LVS100 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.
