  • Application

    The Nivector capacitive point level switch is suitable for all kinds of powdered and fine-grained solids (e.g. plastic granulates, washing agents and animal feed). Because of its materials of construction, Nivector is also suitable for use with foodstuffs such as grain, sugar, herbs and spices or semolina.

    Function

    The sensor surface ofthe Nivector evaluates the different dielectric values of air and bulk solids. If the bulk solids come into contact with the sensor surface, the electronics change the switch status. The Nivector can be switched to either minimum
    of maximum fail-safe mode, ensuring quiescent current operation in all applications. The switch status is indicated by an LED. A guard electrode eliminates interference factors due to the vessel wall or possible build-up,
    for example.

    Application Example

    1: Overfill protection or upper level detection (MAX)
    2: Dry-running protection or lower level detection (MIN)
