NIVELCO LEVEL SWITCHES - VIBRATION ROD - NIVOCONT R - 2

GENERAL DESCRIPTION AIU The NIVOCONT R series of vibrating rod level switches are robust instruments designed for low and high level indication of granules and powders with a minimum of 0.05 kg/dm3 density. Mounted on tanks, silos or hopper bins it can control filling / emptying, or give fail-safe alarm signals. The highly polished version is recommended to use for abrasive mediums. The operation principle is based on that the electronic circuit excites a vibration in the rod probe. When the medium reaches and covers the rod, its vibration stops, when the medium leaves the rod it returns to...

INSTALLATION The probe should be protected against strong material inflow by appropriate selection of the mounting position or by using an overhead protective shield. When the instrument is mounted on the side of the tank, coning or arching of the material should be taken into consideration. In dusty mediums the inclination of the side mounted probe should be greater than the angle of repose to ensure self cleaning and avoid deposition of material on the vibration rod switches. Avoid mounting the unit close to the filling entry or near to medium accumulation. Distance between the probe and...
