Overview
Pointek CLS300 (digital version) is an inverse frequency shift ca-
pacitance level and material detection switch with optional rod/
cable choices and configurable output. It is ideal for detecting
liquids, solids, slurries, foam, and interfaces in demanding con-
ditions where high pressure and temperatures are present and
has the ability to tune out buildup on the probe. The digital ver-
sion includes PROFIBUS PA, an LCD display, and advanced di-
agnostic features.
■
Benefits
• Active-Shield technology so measurement is unaffected by
material buildup or nozzle interference in active shield section
• Performs in extremely abrasive conditions because of solid
rod construction
• Push-button calibration, full-function diagnostics
• 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)
■
Application
Pointek CLS300 digital version provides an integral LCD display
for stand-alone use, with PROFIBUS PA communication
(Profile version 3.0, Class B) when required. Solid-state switch
alarm is standard.
The robust design of CLS300 makes it specifically applicable for
heavy solids applications where abrasive materials occur as in
the mining industry.
The fully potted electronics are unaffected by condensation,
dust or vibration.
Wetted parts are made of stainless steel with a PFA shield for
high chemical resistance, and of ceramic and stainless steel for
high temperature version. Materials with low or high dielectric
constants can be accurately detected. The unique Active Shield
suppresses interference from material buildup or long installa-
tion nozzles.
The unique modular design of the Pointek CLS300 provides a
wide range of configurations, process connections, extensions
and approvals to meet the temperature and pressure require-
ments of specific applications. The modular design makes or-
dering easier and reduces stocking requirements. A wide range
of probe configurations are available, including rod and cable
versions.
• Key Applications: liquids, slurries, bulk solids, relatively high
pressure and temperature, hazardous areas, milling and
mining applications

Configuration
Installation
Keep unit out of path of falling material, or protect probe from
falling material.
Build up of material in active shield area does not affect
switch operation.
Install probe at least 50 (2) from tank wall.
Note angle of repose and adjust accordingly.
