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.
Highlights:
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
Very fast response times
Maintenance-free ‐ can be installed in any position
Wide variety of hygienic process connections available
Also available with a sliding connection for tanks with thick wall thickness / insulation or to overcome high process temperature
EHEDG and 3A certified; complies with FDA and EC1935/2004
Applications:
Small tanks in hygienic applications
Tanks with tough, pasty or strongly adhesive media
Overflow protection, high/low-level detection, dry-run or pump protection in tanks
Interface detection
Detection of foam
Blockage prevention
Media recognition
