Description

● Very small installation width, therefore very narrow pipe work is possible ● Mo moving parts in the medium being monitored ● Installation largely independent of nominal width Characteristics The EFK2 flow switch controls the flow speed of fluid media. Its compact form combines the built in sensor, a two-colour LED status display, and a switching point which can be set using a potentiometer; it has push-pull or relay output. A flexible gooseneck can be installed between the sensor and the electronics housing, so that the best possible view of the flow switch display is provided even in awkward installation locations. Handling and operation Installation Installation must be such that the flow impinges on the marking (X) on the sensor. For sensors with screw-in threads, PTFE tape or sealing paste can be used for the seal. The installation location should be selected so that reproducible flow conditions are achieved (sufficient run-in length, wherever possible no valves, kinks, bends, etc directly ahead of the sensor. A sieve just upstream of the sensor may have a beneficial effect on reproducibility. Operation The flow is raised to the limit value, and the switching point is determined by turning the potentiometer to the point where the LED just switches from red to green (teaching). LED red: Flow rate Limit value Accessories ● Cable/round plug connector (KB...) see additional information “Accessories” ● made-up cable ● T-pieces for system connection Ø13.2 ● Weld-on adapter for insertion sensor Ø12 ● Compression fitting for insertion sensor Ø12 Flange for insertion sensor Ø12
