Senseca EFK2-015HK029OS Flow Switch

Flow Switch EFK2Materials medium-contact Materials, nonmedium-contact Weight Conformity1.4571 1.4305 approx. 0.3 kg CEDimensions● Very small installation width, therefore very narrow pipework is possible● Mo moving parts in the medium being monitored ● Installation largely independent of nominal widthCharacteristics The EFK2 flow switch controls the flow speed of fluid media. Itscompact form combines the built-in sensor, a two-colour LED status display, and a switching point which can be set using apotentiometer; 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.Technical data Sensor Process connection Metering range Measurement accuracyDynamics Pressure resistance Media temperature Ambient temperature Temperaturegradient Supply voltage Current consumption Switching outputOutput loading Display Adjustment potentiometer Electrical connection Resistant to shortcircuits Reversal polarity protected Ingress protectioncalorimetric measurement principle screw-in thread G 1/4 A..G 1/2 A, push-in sensor Ø12 mmwater 2..150 cm/s or 3..300 cm/s oil available on request ±10 % of full scale value1..3 seconds in waterPN 100 bar optionally PN 200 bar 0..70 °C -20..+70 °C 4 K/s 24 V DC / AC ±10 %max. 70 mA galvanically separated relay contact or "push-pull" transistor output (resistant toshort circuits and reversal polarity protected) 2 A / 30 V DC/AC max. for relay,100 mA / 24 V max. for transistor output red / green LED (red < limit value, green > limit value)as inputGooseneck option A gooseneck (optional) the electronics head primary sensorcomplete freedom orientation and reading of the sensor.between and the provides in the directionfor round plug connector M12x1, 4-pole yes yesIP 65pi-ho_fka-efk2_e V1.01-001
