Siemens Milltronics Pointek CLS300 Capacitance Level Detection Switch

Siemens Pointek CLS300 is an inverse frequency shift capacitance level switch, ideal for detecting liquids, solids, slurries, foam and interfaces in demanding conditions where high pressure and temperatures are present. The fully potted electronics are unaffected by condensation, dust or vibration. Its robust design makes it usable in heavy solids applications where abrasive materials exist. 

The CLS300 is offered in standard and digital versions. The standard version has three LED indicators with basic relay or solid-state switch alarms. The digital version provides a solid state switch alarm, an integral LCD display for standalone use, and PROFIBUS PA communication (Profile v3.0, Class B).

Key Specifications

  • Patented Mercap Active Shield Technology
  • High-Sensitivity Probe Unaffected by Material Buildup
  • Withstands Temperatures to 752°F, Pressures to 511 PSI, and High Loads of Solids Materials
  • Works with Highly Abrasive or Corrosive Media
  • Performs Equally Well in Conductive or Non-Conductive (Dielectric=1.5) Viscous Materials
  • Fast, Cost-Effective Setup Using LED's Verification
  • Universal Power Supply and Transmitter
  • Multiple Outputs
