Details:

FE2  FE22  FE7 FE8Standard electrodes are in 316SS, titanium or Hastelloy. Suitable for chemicals such as hydrochloric acid and sulfuric acid, as well as purified water.No affection from suspended solids between electrodes as only the end of the electrode is exposed to process and the other portion is isolated.
Plastic terminal box and flange are rugged. The cover requires no screws or bolts for easy handling.

Principle of Operation

The sensor operates in combination with a relay unit.
Without conductive liquid between electrodes, no current flows. With conductive liquid between electrodes, current flows.
The relay opens or closes its contacts depending on the presence or absence of the current. The relay unit RE7000 supplies small alternating current, so the sensor offers long service life without erosion.
