ES 2001 — conductive level switch

• For all conductive liquids • Sensitivity, delay and operating mode settings • Compatible with all our electrodes Minimum/maximum level control for conductive liquids Overflow / dry-running alarm Filling or emptying function On/off between 2 electrodes Control between 2 levels by self-holding The ES2001 relay works on the conductive principle: the electrical conductivity of the liquids being monitored serves as the electrical connection between the immersed electrodes. Application limit Not suitable for liquids containing oil or grease, or in which electrically insulating deposits may form. Measuring ranges For use with liquids whose resistance between the electrodes is below 150 kΩ. (Observe the maximum cable length!)
