Siemens Pointek CLS500 Capacitance Point Level Switch

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. Patented Active-Shield technology ensures that measurement is unaffected by vapors, 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. The CLS500 is ideal for application sin foam or liquid/foam level, glycol regenerators, high pressure coalescers, and liquefied natural gas (LNG) applications.

Key Specifications

  • Applications in high pressure and temperature, chemically aggressive, and other extreme process environments; Viscous, conductive, and non-conductive liquids, solids, slurries, and interfaces
  • Local display for commissioning and service. Remote adjustable programming and control via HART, with a full range of local and remote diagnostics
  • Patented Active-Shield technology so measurement is unaffected by material buildup in active shield section
  • Two-wire loop powered with solid-state switch or 4 to 20/20 to 4 mA output
  • General purpose, dust ignition proof, explosion proof and intrinsically safe approved models
