OPTISWITCH 6500 C – Version with Tri-clamp connection

Capacitance level switch OPTISWITCH 6500 C – Version with Tri-clamp connection

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.

Product 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

Typical 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
