Starting in November 2017, the new NK411/412 controllers are available in a slim design. The newest generation offers even more safety when it comes to tanks. What does that mean? It means the level controllers have an ex-intrinsically safe probe circuit, are fail-safe, and can be universally serviced. Whether a 24V DV voltage or a 230V AC voltage, it’s not a problem for the NK41x! In combination with the tried and true electro-optical Hecofill level sensors, Hectronic therefore offers a maximum of safety in the monitoring of liquid level limits – both in the storage as well as handling of liquids that are dangerous to the environment.
