Siemens G 2009 Overview Configuration is a compact 2-wire inverse frequency shift capacitance switch for level detection in constricted spaces, interfaces, solids, liquids, slurries and foam. Benefits 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 pplication s short insertion length of 100 mm (4") 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) (7ML01), and -10 to +100 C (+14 to +212 F) (7ML610). 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 is available in three versions. The integral cable version has a stainless steel process and probe options of PPS or PVDF. The fully synthetic version has a thermoplastic polyester enclosure with a PPS process combined with a PPS probe. The standard enclosure version has a thermoplastic polyester enclosure with a stainless steel process in combination with a PPS or PVDF probe. Key pplications: liquids, slurries, powders, granules, food and pharmaceuticals, chemicals, hazardous areas installation /10 Siemens FI 01 2010
