Siemens Process Instrumentation Inverse Frequency Shift Capacitance Switch For Level Detection Pointek CLS200

Overview Pointek CLS200 (standard version) 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. 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 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 (EMC regulations applicable in some regions). Key Applications: liquids, slurries, powders, granules, pressurized applications, hazardous areas
