CROUZET has released the ENRM level control relay, covering the largest possible range of applications. It is available from ITC Products .
The relay covers a range from 250Ω to 1MΩ. It can control the filling and emptying of tanks and can be adjusted for one or two levels. A time delay function 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.
It has two buttons. The first selects the resistivity range (high, medium or low). The second allows fine tuning of the setting. If the liquid is liable to foam, the relay is set by trial and error during commissioning. It has a standard 22.5mm housing with a DIN rail mounting.
