Pointek CLS200 is a versatile inverse frequency shift capacitance level switch with optional rod/cable choices and configurable output, ideal for detection of liquids, solids, slurries, foam and interfaces. The digital version (with PROFIBUS PA) includes a display and provides additional diagnostic features.
The Pointek CLS200 is offered in standard and digital versions.
The standard version has 3 LED indicators with basic relay and solid-state switch alarms.
The digital version provides an integral LCD display for standalone use, and also provides PROFIBUS PA communication (Profile version 3.0, Class B) for connection to a network.
The power supply is galvanically isolated and accepts a wide range of voltages (12 to 250 V AC/DC for standard version and 12 to 30 V DC for digital version). The stainless steel and PPS (PVDF optional) materials used in the probe construction provide a temperature rating up to +125 °C (+257 °F) on the process wetted portion of the probe. The switch responds to any material with a dielectric constant of 1.5 or more by detecting a change in oscillating frequency, and it can be set to detect before contact or on contact with the probe.The CLS200 operates independently of the tank wall or pipe so it does not require an external reference electrode for level detection in a non-conductive vessel such as concrete or plastic.
Key Applications: liquids, slurries, powders, granules, pressurized applications, hazardous areas.
Benefits

Potted construction protects signal circuit from shock, vibration, humidity and/or condensation
High chemical resistance
Level detection independent of tank or pipe earth reference
Insensitive to product buildup due to high frequency oscillation
3 LED indicators for sensor status, output status, and power

Application
Pointek CLS200 standard version has 3 LED indicators with basic relay and solid-state switch alarms. The power supply is galvanically isolated and accepts a wide range of voltages (12 to 250 V AC/DC). When used with thermal isolator, the stainless steel and PPS (PVDF optional) materials used in the probe construction provide a temperature rating up to 125 °C (257 °F) on the process wetted portion of the probe. The switch responds to any material with a dielectric constant of1.5 or more by detecting a change in oscillating frequency, and it can be set to detect before contact or on contact with the probe. The CLS200 operates independently of the tank wall or pipe so it does not require an external reference electrode for level detection in a non-conductive vessel such as concrete orplastic (EMC regulations applicable in some regions).
