Level controller NW-400

 

Level controller for level monitoring or maximum value measurement.

 

Universal basic device with all standard functions for level control, such as run-dry protection, filling control and overflow protection. A wide range of regulatory or report functions can be controlled via the built-in switch contact.

A second measuring channel can be used, for example, to control two different regulating or reporting devices or to monitor two different levels.

Sensitivity to media with different degrees of conductivity can be adjusted via a front-mounted potentiometer.

 

  • Two independent measuring channels
  • One potential-free switching contact per channel
  • Adjustable sensitivity
  • adjustable switch-on delay
  • Measuring channel 1
    Level control alternatively with 3 or 2 electrodes:
    - 2 electrodes: for measuring maximum values
    - 3 electrodes: for monitoring level (min/max)
  • Measuring channel 2
    can be used alternatively for limit or alarm monitoring
