CROUZET has released the ENRM 22.5mm level control relay. The relay covers a range from 250Ω to 1MΩ and two buttons on the front panel allow its sensitivity to be adapted to the resistance of the liquid to be detected.
It can control the filling and emptying of tanks and can be adjusted for one or two levels. A time delay function on the panel can take into account the effects of any waves formed during filling or emptying.
The ENRM has been designed to be suitable for the maximum number of applications by covering the sensitivity range of at least three products.
The first button allows the user to select the resistivity range (high, medium or low). The second button allows the setting to be fine-tuned. If the liquid is liable to foam, the relay is set by trial and error during commissioning.
