The new NIVOROTA rotary paddle level switch series of well-known NIVELCO design can be used for detecting the level of lumpy or
powdery materials and granules. Mounted to tanks, silos and hoppers it can monitor and control level, flling and emptying of stored
materials such as stone, fly ash, sand, coal, feed, beet slice, etc. A small power electric motor drives the paddle which rotates freely in the
absence of the material. When the paddle is immersed by the material reaching it, the motor will be switched off the same time triggering
the output contact switch. When the material level drops the paddle runs free again, the motor is reactivated and the switch returns to its
original state. The new series NIVOROTA E-700 & E-800 rotary paddle level switches provide all the advantageous features of the previous
series in one unit. Dust Ex versions are available for use in hazardous environments.
