NL2750
2-point controller with switchable inflow/outflow function
The NL2750 is an electronic two-step controller which complies with the required safety regulations. It works based on the principle of conductive measuring i.e. it uses the electrical conductivity of the liquid to determine the level by means of a probe (electrode). Depending on the conductivity of the medium, controller types with high, normal or low sensitivity must be used.
Application examples:
Water containers, tanks, boilers, separation plants, bain-marie, boiling kettles, pressure vessels, pump dry run protection, filling controls, flow monitoring, inflow and outflow metering, leak detection, overfill protection, swimming pools, dishwashers, washing plants, washing machines, water treatment etc.
