Pointek CLS 100 is a compact two-wire reverse frequency shift capacitive switch suitable for detecting interfaces, liquids, slurries and foams in applications where space is limited. It features easy installation, no moving parts, low maintenance, adjustable sensitivity, built-in cable type or PBT housing, intrinsically safe, dustproof and explosion-proof and ordinary types.
The Pointek CLS100 is a compact two‑wire capacitive level switch designed for detecting interfaces, liquids, slurries and foams in space‑constrained installations. It offers LED indication, no moving parts, and selectable probe materials (PPS, PVDF) with options for standard, explosion‑proof, and intrinsically safe versions.
The manual covers product features, technical specifications, wiring and output options (4‑20 mA, 0‑20 mA, transistor), installation guidelines, certification details (IP68, ATEX, IECEx) and ordering information, helping users integrate the switch safely and reliably into their processes. This manual is written in Chinese.
