Pointek CLS200 – Digital
Contact
Pointek CLS200 (digital version) is a level switch for liquids, solids, slurries, foam, and interface detection. It features an LCD display, PROFIBUS PA communication, and supports optional rod or cable probe configurations.
Key Features
-
Fully potted electronics, providing protection from shock, vibration, humidity, and condensation
-
High chemical resistance with probe constructed from stainless steel and PPS (optional PVDF)
-
Operates independently of vessel or pipe grounding—ideal for use in plastic or concrete tanks
-
Immune to material buildup thanks to high-frequency oscillation
-
High sensitivity, suitable for media with a dielectric constant ≥ 1.5
-
Integrated LCD display with menu-driven interface for easy configuration
-
PROFIBUS PA digital communication (Profile 3.0, Class B), compatible with SIMATIC PDM software
-
Galvanically isolated power supply, accepts 12 to 30 V DC
-
Supports configuration of alarm behavior, signal delay, and precise switching point
Typical Applications
-
Level detection in liquids, slurries, and foams
-
Suitable for powders, granules, and bulk solids
-
Ideal for pressurized systems or hazardous area installations
-
Excellent performance in non-conductive tanks (e.g., plastic or concrete)
-
Seamless integration into PROFIBUS-based systems for remote diagnostics and configuration
Additional Information
When used with a thermal isolator, the wetted part of the probe can withstand process temperatures up to 125 °C (257 °F). The sensor can be configured to detect either pre-contact proximity or direct contact with the material. PROFIBUS network integration enables full access to diagnostic capabilities and remote operation via SIMATIC PDM.

Footnotes:
- When used in hazardous areas, operational limits must follow the relevant certificate. See CLS200 pressure/temperature curves.
- Thermal isolator must be used if the process temperature exceeds 85 °C.
- Pressure rating depends on temperature. See pressure/temperature curves.
- Intrinsically safe operation requires suitable power supply or barrier.
