Overview
Pointek CLS100 is a compact, 2-wire, inverse frequency shift capa
citance 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
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
Application
Pointek CLS100’s short insertion length of 100 mm (4 inch) 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, 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 poly
ester 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
