All advantages & materials at a glance

High flexibility: Modular configuration of materials, threaded connections, shapes and float sizes

Small space requirement: Slim design for compact tanks and confined installation situations

Energy efficient: Reed technology requires no permanent power supply

Adaptable switching logic: For many articles, flexibly selectable as normally closed, normally open or changeover (NO/NC/CO) by float rotation or switching module

Versatile sensor outputs: From simple limit value switching signals to analog 4–20 mA output with high resolution

Flexible configuration – tailored to every application

Several variants are available for maximum adaptability:

  • 1 switching point – for simple level detection
  • 2 switching points – for simultaneous monitoring of minimum and maximum levels
  • More than 2 switching points – for sophisticated, multi-stage level controls

Variety of materials for different media

To ensure that the switches are ideally suited to your process media and ambient conditions, they are available in various high-quality materials:

  • PP (polypropylene) – chemically resistant and versatile
  • PVC (polyvinyl chloride) – economical, robust and media-resistant
  • PVDF (polyvinylidene fluoride) – for aggressive media and high requirements
  • NIRO 1.4571 (stainless steel) – extremely durable and temperature-resistant
