Pointek CLS200 (digital 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. The digital version includes PROFIBUS PA, an LCD display, and advanced diagnostic features.
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
High sensitivity allows installation in a wide range of liquids, solids or slurry applications
Integral LCD display allows for easy menu-driven setup
PROFIBUS PA communication (SIMATIC PDM compatible)
Pointek CLS200 digital version provides an integral LCD display for stand-alone 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 30 V 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 menu-driven setup allows precise control of the switch point signal damping and alarm functions.
When connected to the PROFIBUS network, advanced diagnostics and set up using SIMATIC PDM are possible.
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
