Paddle flow switch UR.-0 series

magneticreed switchfor water

The devices function via the principle of a spring-supported paddle, and the magnetic triggering of a reed switch. Ranges Details in the table correspond to horizontal inwards flow with decreasing flow rate. UR2 (Plastic switching unit) is adjusted in the factory; please specify switching value. Handling and operation Note ●Include straight calming section of 5 x DN in inlet and outlet ●If the media are dirty, install a filter (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 UR1 - loosen bolts, push the switching current tube into the desired position. Retighten the bolts. Normally closed (n.c.) or normally open (n.o.) as per table "Technical data" Options ●Switching ranges for oil or gas ●Special quantity ●Adhesive PVC fitting Ordering information ●Specify direction of flow, medium, and switching range, UR1 or switching value UR2. ●For UR2 specify normally closed (n.c.) or normally open (n.o.). ●For oils, state viscosity, temperature and designation (e.g. ISO VG 68) (enquire about range). ●For gases, state pressure (relative or absolute), temperature and medium (e.g. air) (enquire about range).
