Siemens CLS 300
Pointek CLS300 (digital version) is an inverse frequency shift capacitance level and material detection switch with optional rod/cable choices and configurable output. It is ideal for detecting liquids, solids, slurries, foam, and interfaces in demanding conditions where high pressure and temperatures are present and has the capability to tune out build-up on the probe. The digital version includes PROFIBUS PA, an LCD display, and advanced diagnostic features.
Pointek CLS300 digital version provides an integral LCD display for stand-alone use, with PROFIBUS PA communication (Profile version 3.0, Class B) when required. Solid-state switch alarm is standard. The robust design of CLS300 makes it specifically applicable for heavy solids applications where abrasive materials occur, as in the mining industry. The fully potted electronics are unaffected by condensation, dust, or vibration. Wetted parts are made of stainless steel with a PFA shield for high chemical resistance, and of ceramic and stainless steel for the high temperature version. Materials with low or high dielectric constants can be accurately detected. The unique Active Shield suppresses interference from material build-up or long installation nozzles.
The unique modular design of the Pointek CLS300 provides a wide range of configurations, process connections, extensions, and approvals to meet the temperature and pressure requirements of specific applications. The modular design makes ordering easier and reduces stocking requirements. A wide range of probe configurations are available, including rod and cable versions.
Key Applications: liquids, slurries, bulk solids, relatively high pressure and temperature, hazardous areas, milling and mining applications.
