Level-Relays NS20K for conductive liquids can be used as monitors for 1 Level and for controlling a level between 2 electrodes.

  • 3 elektrodes for MIN/MAXcontrol
  • 2 elektrodes (E2 open) as level monitor
  • Sensitivity adjustable 5 kΩ…250 kΩ
  • LED for state of relay
  • Function of relay reversible (picks up or releases at top electrode)
  • Switching-delay adjustable 0,1…10 s
  • Housing 35 mm wide, mounting height 55 mm
  • Universal supply-voltage AC/DC 24-240 V

Application level monitor

Protection from running dry or overflow, monitoring of pumps for leaks, detection of leaks.

Application Min/Max

Controlling a level between minimum (electrode E2) and maximum (E3). As long as E3 is dry, a magnetic valve is opened (or a pump is running) and liquid is influencing. As soon as maximum
(E3) is reached, the NS20K closes the valve. When the level falls below E2, the cycle starts new. In reverse also discharging of a container can be controlled.
