Capacitive level switch SB series

To avoid false alarms due to highly viscous medium sticking to the probe, a special material is added between the active section and the grounded section that acts as an insulating electrode. Because the electric field between the active section and the protective section is circular in shape, no current will flow through the medium between the electrodes.This product offers a DPDT output for high or low level detection, adjustable delay, and adjustable sensitivity. Various models are available for e.g. high temperatures, or limited installation space.
