Application Pointek CLS100’s short insertion length of 100 mm (4") and ver-satility in various applications and in vessels or pipes makes it a good replacement for traditional capacitance sensors. Its advanced tip-sensing technology provides accurate, repeat-able switchpoint performance. The PPS (Polyphenylene sulfide) probe [optional PVDF (Polyvinylidene Fluoride)] is chemically re-sistant with an effective process operating temperature range from -40 to +100 °C (-40 to +212 °F) (7ML5501), and -20 to +100°C (-20 to +212 °F) (7ML5610). The fully potted design en- sures reliability in a vibrating environment such as agitated tanks up to 4

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 connec-tion 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
