The OPTISWITCH 6600 is a capacitance level switch for hygienic and industrial applications. The switch detects high or low level or serves as overfill, dry-run or pump protection. The device can also detect liquid-liquid interfaces or a change of media characteristics. It operates independently of the mounting position. With a reverse thread, it can be mounted into an extension tube for a top-mounted low level detection. The microwave level switch is resistant to CIP and SIP agents.
