Pointek CLS500

The Siemens Pointek CLS500 is an inverse frequency shift capacitance level switch for detecting interfaces, solids, liquids, toxic and aggressive chemicals in critical conditions of high temperature and pressure.

Active-Shield technology ensures that measurement is unaffected by vapours, product deposits, dust and condensation. The unique mechanical probe design coupled with a high-performance transmitter gives superior performance in a wide range of level detection applications.

Pointek CLS500’s microprocessor-based electronics provide one-point calibration, making setup possible without shutting down your production process.


  • Active-Shield technology so measurement is unaffected by material buildup in active shield section
  • 2-wire loop powered with solid-state switch or 4 to 20/20 to 4 mA output
  • Simple push-button calibration and integrated local display
  • Full function diagnostics
  • HART communications for remote commissioning and inspection
