Afriso South Africa (Pty) Ltd
Conductivity level switch - CoFox® ELT 68
Suitable for use with electrically conducting materials, predominantly liquids, e.g. milk, wine, fruit juices, waste water or lyes. Also suitable for foaming or adhesive media, e.g. beer or yoghurt. Specially designed for applications in the food industry.
The CoFox® ELT 680 level controller operates on the basis of conductivity.
The built-in timer can be set to avoid undesired switching as a result of surface turbulences.
The sensitivity and adjustment range of the controller have been designed to ignore bridging resistances which could impair the reliability of the unit (e.g. foam across the electrode insulators in breweries, dairies and ice-cream plants).
Furthermore, the unit is capable of interface detection between liquids with different levels of conductivity (e.g. water and milk) in pipes and tanks.
Switching functionsThe unit can be used with either one electrode as a single point controller or with two electrodes for pump “on-off“ control.
