Magnetic flow switch UR3K-…V

paddlefor oilfor aggressive media

The devices function via the principle of a spring-supported paddle, and the magnetic triggering of a reed switch. ●Soldered/welded connection ●Reed switch ●Low pressure loss ●Compact design ●Threaded connection ●Plug DIN 43650-A / ISO 4400 Handling and Operation Note ●Include straight calming section of 5 x DN in inlet and outlet ●When tightening the union nut, the connection piece must be countered using an open-ended spanner (SW 19). ●Include a filter if the media are dirty (use magnetic filter for ferritic components). ●It must be ensured that the values given for voltage, current, and power are not exceeded. ●When switched on, a load must be connected in series. ●The electrical details apply to ohmic loads. Capacitive, inductive and lamp loads must be operated using a protective circuit. Adjustment To adjust, open the slider. Adjustment is made using the adjustment screw with a lengthways slot; this is located under the valve. Turn clockwise for a lower switching point; turn anticlockwise for a higher switching point. After adjustment, close the slider again. Example: The adjustment range 20 to 27 l/min corresponds to 7 l/min Adjustment option in 7 revolutions. Adjustment is therefore 1 l/min for each revolution. Options ●Connection for round plug-in connector ●Signal lamp red or red/green in the plug DIN 43650-A ●Protective bellows ●Switching ranges for oil or gas ●Special quantity ●Adhesive PVC fitting
