SMC LFE1K4N2 Electromagnetic Type Digital Flow Switch

LFE, Digital Liquid Flow Sensor, Electromagnetic, 2-Screen 3-Color Display, IP65, 0.5-200 Lpm

LFE is a digital flow sensor for water and non-corrosive conductive liquids. While the PF3W sensors detect flow using the Karman vortex principle, LFE applies Faraday s law of induction. There are no obstacles or moving parts in the flow path, yielding a smaller pressure loss which saves pumping energy. Detectable liquids have fewer viscosity restraints. Finally, the flow direction can be changed after installation. The 2-screen, 3-color display can show the measured value in the primary screen, while viewing a variey of secondary data in the sub-screen. Two outputs are available, including two switch signals, or a switch and analog signal. Options include a mounting bracket and M12 lead wire. Piping connections are C37 brass as standard, while the -X8 option offers 304 stainless steel. LFE is IP65 rated, and CE and RoHS compliant.
