PA6, IP 66, temp. -40º C/+120ºC, P=-1/+16 bar, supply 21-230VAC/21-45VDC, DPDT, G1, L=155mm

RFnivo® Capacitive Limit Switch

The RFnivo® level limit switch is universally applicable in solids and liquids as a full, demand or empty detector in silos and containers. The different device versions withstand extreme process conditions and due to their stainless steel components, are very robust.

The RFnivo® measures the capacitance between the probe and container wall.  If the probe is covered by the product, the measured capacitance changes and a switching signal is activated.
