Use

Detection by conductivity provides a simple and economical solution for detecting levels for electrically conductive products, even if their conductivity is low. Conventional applications: High level security, Protection of pumps against dry running, control between a minimum and a maximum. Different combinations of electrodes provide a variety of applications:

  • Detecting one or more levels in a tank,
  • Regulation between two levels in a tank, etc.

 

2. 2. The Probe, matched to the specific features of the installation - temperature, pressure, type of fitting, length, etc. - comprises:

  • An electrical connection head,
  • A process fitting: Flange, Threaded Coupling, Clamp connection, etc.
  • One or more electrodes, rigid or cabled.

 

Functions

The Electronic Detector delivers an alternating current which crosses the circuit formed by:

  • an ELECTRODE set to the level to be detected,
  • one Reference ELECTRODE (which may be the tank itself),
  • the detected LIQUID, which must be electrically conductive, even slightly.

When the LIQUID closes the circuit between the electrodes, the current acts on the Detector and its relay output (changeover contact) gives an alarm, control or regulation.
