Bamo Resistive Level Controller ES 2001 | Descriptions

Probes and electrodes are specially designed for different type of applications. Level Controller ES2001 is used as a limit value detector on conductive liquids; Probes and rods are chosen according to the application. Detection sensitivity to different type of liquids is set through the built-in potentiometer from 1 to 150 kΩ.

The hysteresis between on/off switching of output relay is about 20% of sensibility. Such a narrow hysteresis limits false detection by a leakage current due to presence of mist, foam or condensed vapors.

With both timers, it is easy to adjust the level detection or level regulation to prevent false triggering due to wave effects. For level detection, 1 relay ES2001 is necessary for each independent trigger point.


  • For all electrically conductive liquids
