The OPTISWITCH 6700 is a capacitance level switch for hygienic and general industrial applications requiring IO-Link communication. It detects high or low level and is therefore ideally suited for overfill and empty tank prevention or for dry-run protection of pumps. The device is also designed for the detection of liquid-liquid interfaces or change of media characteristics.
