Weber Sensors, 4120.12M, Flow-Captor Switch, PNP N.C. Opener Current-Carrying, Water-Based
Features:
- Precise switching sensor for water- and oil-based media up to 100 bar
- High accuracy even under low flow condition
- Separate adjustment for range and set-point
- Analog display of actual flow and display of the adjusted set-point
- LED-display of output status
- ISO 9001 : 2008
The flow-captor 412x.1xM is a further development with an additional pressure resistance. This highly accurate metering - flow switch is used in every industry where flow monitoring - measuring and displaying liquid media is of importance. With this flow-captor it is possible to set an exact flow set-point and simultaneously measure the flow speed, even up to very low flow conditions.
Sensor head:
The sensor head is constructed of only one piece of electro polished stainless steel and without any sensor element intruding into the medium. Easy installation by means of T-piece or welded fitting. For aggressive media special materials as Titanium, Hastelloy, Monel or a special sensor coating can be offered. The electronics inside is completely epoxy resin encapsulated.
