Reliable Automation for Your Level Monitoring
Automatisieren Sie Ihre Füllstandsüberwachung mit hochpräzisen Magnetschaltern von WEKA. Diese robusten Schaltgeräte aktivieren sich zuverlässig, sobald der Flüssigkeitspegel die definierte Schaltposition erreicht. Dank bistabiler Technologie bleibt der Schaltzustand auch nach dem Vorbeifahren des Schwimmers stabil erhalten – perfekt für prozesssichere Automatisierungslösungen und kritische Sicherheitsfunktionen wie Überfüll- oder Leerstandsschutz.
Magnetic Switches
Precise Switching Function Through Proven Magnetic Technology
The rod magnet integrated in the float activates the reed contact in the magnetic switch precisely when the switching position is reached. The bistable design ensures a stable switching state, even when the float leaves the position again.
External mounting on the standpipe enables retrofit installation without process interruption. The contactless magnetic technology creates no wearing parts in the switching area – for maintenance-free long-term operation.
The clear switching signals can be seamlessly integrated into PLC, control systems or local controls, providing maximum flexibility for your automation solutions.
Explosion protection versions
Ex i (intrinsically safe): For zones 0, 1, 2 – energy limitation prevents ignition
Ex d (flameproof): For zones 1, 2 – flameproof enclosure encapsulates sparks
Certification: Type-tested according to ATEX and IECEx
