ENDRESS+HAUSER FTL31-AA4U3AAWBJ Vibronic Level Switch, 10 to 30VDC, 3-Wire PNP, G1/2, 316L Stainless Steel, M16 Valve Plug, IP65

FTL31-AA4U3AAWBJ is a Vibronic, Liquiphant FTL31, point level switch for liquids. This point level switch is used in tanks, vessels, and pipes. It is used for overfilling protection or pump protection in cleaning and filter systems as well as in cooling and lubrication vessels, for instance. Ideal for applications in which float switches or conductive, capacitance and optical sensors have been used up to now. The Liquiphant FTL31 also works in areas where these measuring principles are not suitable due to conductivity, buildup, turbulence, flow conditions or air bubbles. It features operational safety, reliability and universal application thanks to the tuning fork measuring principle. It has a compact design for easy installation even in confined conditions or hard-to-access areas.
