Conductivity

Conductivity Level Switch

This unit is designed for simple pump control or alarm indication. The electrodes are mounted on the tank top via their holders (EA18) and St/St rod is fitted to suit the required switch points.

The electronic level controls together with resistive probes are suitable for the control and monitoring of the levels of conductive liquids. The operation of the controller is dependant on the conductivity of the liquid. It is therefore not suitable for use with liquids such as gas oils, lubricant oils, petroleum and oil derivatives etc. The level is determined by the length of the electrodes linked to the controller.

The controller case is manufactured from shock resistant thermoplastic and is designed for side by side multi installation.
