SIEMENS Hot Sale Capacitance level switch Pointek CLS100 Process Instrumentation 

Level Measurement Point Level New & Original 






Pointek CLS100 is a compact, 2-wire, inverse frequency shift capacitance switch for level and material 

detection in constricted spaces, interfaces, solids, liquids, slurries, and foam; with the ability to tune out buildup on probe.



  • Easy installation with verification by built-in LED

  • Low maintenance with no moving parts

  • Sensitivity adjustment

  • Integrated cable or PBT enclosure versions available

  • Intrinsically Safe, Dust Ignition Proof, and General Purpose options available



Pointek CLS100’s short insertion length of 100 mm (4 inch) and versatility in various applications 

and in vessels or pipes makes it a good replacement for traditional capacitance sensors.

Its advanced tip-sensing technology provides accurate, repeatable switchpoint performance. 

The PPS (Polyphenylene sulfide) probe [optional PVDF (Polyvinylidene Fluoride)] is chemically resistant 

with an effective process operating temperature range from -30 to +100 °C (-22 to +212 °F) (7ML5501), and -10 to +100 °C (14 to 212 °F) (7ML5610). 

The fully potted design ensures reliability in a vibrating environment such as agitated tanks up to 4 g. 

When used with a SensGuard protection cover, the CLS100 is protected from shearing, impact, and abrasion in tough primary processes.


The Pointek CLS100 is available in three versions. 

The integral cable version has a stainless steel process connection and probe options of PPS or PVDF. 

The fully synthetic version has a thermoplastic polyester enclosure with a PPS process connection combined with a PPS probe. 

The standard enclosure version has a thermoplastic polyester enclosure with a stainless steel process connection in combination with a PPS or PVDF probe.

  • Key Applications: liquids, slurries, powders, granules, food and pharmaceuticals, chemicals, hazardous areas
