In water circuits where switching reliability matters, this flow switch gives operators a clear, adjustable switching point without adding unnecessary installation length. The switching value is continuously adjustable, and the compact design supports installation in pipe sizes from DN 8 to DN 80 with G 1/4 to G 3 internal threads.
The design is made for robust industrial use. Flow lifts a disc unit with magnet against spring force, while magnetic coupling actuates a hermetically separated microswitch. This keeps the switching function protected from the medium and supports repeatable operation, even where dirt in the medium can be a concern.
With switching ranges from 1 to 600 l/min H2O, recommended maximum flow values up to 720 l/min and tolerance of ±5 % of full scale, the family covers a broad range of water applications. The DIN 43650-A / ISO 4400 connector, maximum 250 V AC switching voltage and ingress protection (IP65) support straightforward integration into industrial systems.
Volume flow lifts a spring-loaded disc unit with magnet. The movement actuates a microswitch via magnetic coupling.
The family includes G 1/4 to G 3 internal thread connections for nominal diameters from DN 8 to DN 80.
Standard switching ranges are specified for H2O with horizontal flow and decreasing flow rate.
The device uses a changeover microswitch. Electrical data is specified for resistive loads.
Standard installation uses horizontal flow. Other mounting positions are possible, but they influence the switching point or switching range.
For contaminated media, the source recommends a filter. For ferritic particles, a magnetic filter is recommended.
Special connectors, signal lamps, temperature display, temperature monitoring, higher temperature resistance, metal cover, gold-contact microswitch, oil switching ranges and special flow rates are available on request.
