Regulation and Control of Liquid Levels – ENR300, ETS100-200 and ETS410

Regulation and Control of Liquid Levels – ENR300, ETS100-200 and ETS410

The electronic controllers ENR300, ET100, ETS200 and ETS410 ensure precise control of the liquid level in the tank. These devices guarantee both protection against dry running and optimal level regulation in demanding industrial environments, particularly in surface technologies and electroplating.

Data sheet – ETS100-200-410
  • ENR300:
    • Relay output (MIN/MAX contact) configurable for opening or closing for liquid level control.
    • Additional monitoring of another critical level.
  • ETS100 and ETS200:
    • ETS100: 1 relay output for 1 switching point for MIN or MAX control.
    • ETS200: 2 relay outputs for 2 independent switching points.
  • ETS410:
    • 4 inputs to detect up to 4 independent levels.
    • 4 relay outputs for alerting or transmitting to a PLC.
  • Adjustable sensitivity: 0.05 to 100 kΩ, adaptable to liquid conductivity.
