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.
Unaffected by foam, condensate or build-up
Can be set to detect foam or even a change in media characteristics of the same liquid
For media with dielectric constant >1.5
