Pointek CLS300 RF Capacitance Level Switch

Brand: Siemens Aktiengesellschaft

Free Shipping on Orders Over $500.00 CAD

The capacitive level switches of the Pointek CLS ensure excellent measurement performance, even under the harsh conditions of high-pressure and high-temperature applications.

Pointek CLS300 (standard version) is an inverse frequency shift capacitance level and material detection switch with optional rod/cable choices and configurable output.

CLS300 is ideal for detecting liquids, solids, slurries, foam, and interfaces in demanding conditions where high pressure and temperatures are present and has the ability to tune out buildup on the probe.
Features
  • Active-Shield technology so measurement is unaffected by material buildup or nozzle interference in active shield section 
  • Performs in extremely abrasive conditions because of solid rod construction 
  • Three LED indicators for adjustment control, output status, and power 
  • High-temperature version up to 400° C (752° F)
