WP-DJ Electrode Level Controller

The NOIKE-AH WP-DJ Electrode Level Controller is designed for conductive liquid level monitoring and automatic control in tanks, reservoirs, sumps, and industrial process systems.

The controller is available in integrated and split installation types. The integrated version combines the controller circuit and electrode junction box into one compact unit, while the split version separates the controller and electrodes for flexible installation inside electrical cabinets or control panels.

When used together with pumps, the WP-DJ controller enables automatic liquid filling and draining while providing local level monitoring and alarm functions.

Working Principle

The WP-DJ controller detects liquid level through conductive electrodes installed inside the tank.

When the liquid contacts the electrodes, the controller receives the level signal and performs the corresponding control action according to the selected electrode configuration, such as pump start/stop, liquid filling, liquid draining, or alarm output.

Different electrode combinations provide different monitoring and control functions to suit various industrial applications.
