Endress+Hauser Nivector FTI26 and Liquipoint FTW23 series point level capacitance switches are contact sensors that detect presence by evaluating differences in dielectric values. They detect level of solids or water-based conductive liquids.
Nivector FTI26 series, available in polycarbonate or stainless-steel housings, detect powders or fine-grained bulk solids in silos, hoppers, and bins. Stainless-steel versions are FDA compliant and marked with the 3-A symbol for food industry hygienic applications.
Liquipoint FTW23 series, detects water-based liquids in storage tanks, mixing vessels, and pipes. They are FDA compliant and marked with the 3-A symbol.
Both offer IO-Link compatible models which provide direct access to process and diagnostic data and allow device configuration while in operation.
