The OPTISWITCH 6500 is a capacitance level switch for level detection in hygienic applications or any environment requiring minimally invasive sensors. It detects low or high level and is often used as dry-run or overfill protection. The device is able to detect foam or even a change in media characteristics of the same liquid (e.g. degree of pollution of water). The microwave level switch is resistant to CIP and SIP agents.
