ST-7 flow switches
The ST-7 is a newly developed version of the flow switch having a
completely new operating principle.
In this new development a robust and industrial micro switch is inserted
instead of the usually supersensitive REED-contacts with low switching
capacity.
This micro switch makes it possible to realize a significantly higher electrical
output though having a longer working life.
The electrical and water-hydraulic components of the flow switch are
completely separated.
The construction of the flow switch allows mounting the electrical parts
independent of the hydraulic components within the series production
process.
When fitting together chassis and switch box both parts of the flow switch
3/8" F. Protection class IP65. Cable 1,200 mm. 10 A. 250 V. Inrush current are connected again.
20 A (NC) and 15 A (NO). Max. 350 bar / 45 l/min / 80 °C Due to the mature engineering low switching points are realized in spite of
maximum water quantities.
