---------

Manufacturer: NIVELCO(HUNGARY)

Model:  E-400/500 Series

              NIVOROTA E rotary level switch series of robust design can be used for detecting level of lumpy or powdery materials and granules. Mounted to tanks, silos and hoppers it can monitor and control level, filling 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 impeded by the material reaching it, the motor will be switched off the same time triggering a dry contact control switch.When the material level drops the paddles run free again, the motor is reactivated and the control switch returns to its original position.

Main Features:

• Level switching of free flowing solids
• Cable extended versions up to 3m
• Automatic motor shut-down
• High temperature version
• Dust-Ex versions

Type selection:

 For appropriate model selection the following should be taken into consideration:

• Protrusion length: Level switching application (low or high level switch) and the position of installation determine the protrusion length.
  
• Number of vanes:
  
  • Specific gravity and particle size of the material provides orientation for the number of vanes.
    
  • Most commonly used is the stainless steel, single vane blade. This paddle can be passed through the respective threaded connection.
    
  • For lighter materials the use of 3- or 4-vane paddle is recommended
    
• Flexible coupling: Use if the shaft of the instrument has to be protected against falling mate-rials. (rocks, larger lumpy materials)
