Pointek CLS200 - Standard Capacitance Level Switch
The Pointek CLS200 (standard version) is a versatile inverse frequency shift capacitance level and material detection switch with configurable rod/cable options and output configurations. Ideal for detecting liquids, solids, slurries, foam, and interfaces, this switch features advanced tuning capabilities to ignore buildup on the probe.

Key Benefits
- Potted construction protects signal circuit from shock, vibration, humidity, and condensation
- High chemical resistance for demanding industrial environments
- Level detection independent of tank or pipe earth reference
- Insensitive to product buildup due to high frequency oscillation
- Three LED indicators for sensor status, output status, and power
- Suitable for API 2350 compliance requirements
Applications
The Pointek CLS200 standard version features three LED indicators with basic relay and solid-state switch alarms. This universal switch handles solids, liquids, and interface detection applications. The galvanically isolated power supply accepts a wide voltage range (12 to 250 V AC/DC). When used with thermal isolator, the stainless steel and PPS (PVDF optional) probe materials provide temperature ratings up to 125°C (257°F) on process-wetted portions.
The switch detects materials with dielectric constants of 1.5 or higher by monitoring changes in oscillating frequency, with settings for detection before contact or on contact. The CLS200 operates independently of tank walls or pipes, eliminating the need for external reference electrodes in non-conductive vessels like concrete or plastic.
Primary Applications
- Liquids and slurries level detection
- Powders and granules inventory monitoring
- Pressurized vessel applications
- Hazardous area installations
