Smart Sanitary Level Switch SIS

The sanitary smart level switch (SIS) is used for signaling high and low positions in tanks or pipelines within the production process. Its compact design makes it easy to transport and install, even in confined spaces or challenging working conditions. It is suitable for use in CIP and SIP cleaning applications, with surface roughness (Ra) adjustable to customer requirements. It is ideal for applications in the pharmaceutical and food industries.

Main Features:

  • Easy installation with a standard connection, IP67/IP68/IP69K protection ratings.
  • Compact design, easy to handle; can be installed in narrow spaces or under harsh operating conditions.
  • Magnetic test function to check wiring and real-time operational status.
  • Durable stainless steel housing.
  • Real-time location monitoring with LED indicators.
  • Overcurrent protection detects excessive current and immediately shuts off the output.
  • Suitable for operation in CIP and SIP cleaning environments.
  • Foam and sticky liquids do not affect the sensor.
  • Provides 2 output signals with independently adjustable sensitivity, helping to detect two different substances.

Applications:

  • Food production
  • Beverage production
  • Pharmaceutical manufacturing
