Pointek CLS300 Level Switch

The SIEMENS Pointek, CLS300 level switch, is an inverse frequency shift capacitance level switch with optional rod/cable choices and configurable output. It is ideal for detecting liquids, solids, slurries, foam, and interfaces demanding conditions where high pressure and temperatures are present. The digital version (with PROFIBUS PA) includes a display and provides additional diagnostic features.

The Pointek CLS300 is offered in standard and digital versions. The standard version has 3 LED indicators with a basic relay or solid-state switch alarms. The digital version of the Pointek CLS300 provides an integral LCD for standalone use, with PROFIBUS PA communication (Profile version 3.0, Class B) when required. The 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 or stainless steel with a PFA shield for high chemical resistance. Ceramic inserts are supplied with high-temperature CLS300 devices. Materials with low or high dielectric constants can be accurately detected. The unique Active Shield suppresses interference from material buildup.

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 is available, including rod and cable versions.
