Overview
4
Pointek CLS100 is a compact, 2-wire, inverse frequency shift ca-
pacitance switch for level and material detection in constricted
spaces, interfaces, solids, liquids, slurries, and foam; with the
ability to tune out buildup on probe.
■
Benefits
• Easy installation with verification by built-in LED

Application
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, 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
-30 to +100 °C (-22 to +212 °F) (7ML5501), and -10 to +100 °C
(14 to 212 °F) (7ML5610). The fully potted design ensures reliabil-
ity in a vibrating environment such as agitated tanks up to 4 g.
When used with a SensGuard protection cover, the CLS100 is pro-
tected from shearing, impact, and abrasion in tough primary pro-
cesses.
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
