Controller-level switch ERSU-K2

CONTROLLER-LEVEL switch ERSU-K2

1. The PURPOSE

Controller-level switch ERSU-K2 is designed for alarm and keep within the prescribed limits of water level in steam boilers and for control of other fluids, relevant technical characteristics device.

Normal regulator operation is guaranteed at temperatures air from -10 to +45 º C and relative humidity up to 98% at 50 º C and without moisture condensation.

The appliance is not intended for operation in conditions of:

a) explosive areas;

b) control environments, giving a solid residue on the electrode sensor;

C) effect of shaking and shock.
