Vibrating level switch / for liquids - NIVOSWITCH compact
NIVOSWITCH for liquids - (Compact Vibrating Fork) : LEVEL SWITCHES GENERAL DESCRIPTION:
The NIVOSWITCH compact vibrating fork level switches with parallel vibrating fork are suitable for for level detection of liquids. Mounted on silos, tanks or hopper bins it can control filling / emptying, also can generate fail-safe alarms providing overfill or dry run protection. The operation principle is based on that the electronic circuit excites a vibration in the fork probe. When the medium reaches and covers the fork, its vibration stops, when the medium leaves the fork it returns to vibrate freely. The electronics senses the change of vibration and gives output signal after a selected delay. The plastic coated version is recommended to use for aggressive mediums, the highly polished version is recommended to use for abrasive mediums.
