Endress+Hauser Terms and Conditions
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.
The face of the Nivector unit acts as a sensor. If the solids come into contact with the front face, then the electronics change the switching mode. The Nivector can be switched to either min or max fail-safe mode and a LED indicates its switching status. A screen electrode prevents interference through the container walls or lateral solids build-up.
