Capacitive Level Sensors CLS-23, Dinel

Capacitive level sensors (switches) CLS–23 are designed for limit level detection of electrically conductive and non-conductive liquids in vessels, reservoirs, sumps, pipes, tanks, etc. The sensitivity of the sensor can be easily set by placing a magnetic pen on a sensitive spot.

The process coupling at the housing can be with metric thread (M18x1.5; M20x1.5), pipe thread (G3/8”; G1/2”), or sealing thread (NPT 1/2–14). Output performances – transistor output with the open collector (PNP), two-wire electronic switch (S), and NAMUR output for intrinsically safe connection.

There are next performances available: N – Normal for non-explosive areas, E – Extended temperature range for non-explosives areas, Xi – Explosion-proof (intrinsically safe for explosive areas), NT – High-temperature variant for non-explosives areas, and XiT – High-temperature variant for explosive areas. CLS-23 capacitive level sensors meet the safety integrity level requirements according to standard EN 61508 at level SIL 1.

Features

  • Detection of various types of electrically conductive or non-conductive liquids (water, water solution, cooling liquids, oil, etc.)
  • Sensitivity setting using a magnetic pen
  • Direct mounting into various containers, vessels, tanks, etc.
  • Outputs S, PNP, NAMUR (for explosive areas)
  • High-temperature performance, pressure resistance up to 7 MPa
  • Process coupling – thread M18, M20, G3/8“ or 1/2–14 NPT
  • Xi, XiT versions for usage in explosive areas

Variant of Sensor

  • CLS–23_–10 Uncoated short bar electrode, for sensing the level of electrically non-conductive liquids (oil, crude oil products). Assembly into a sidewall of a vessel or a pipe. Electrode length of 30 mm.
  • CLS–23_–11 Fully coated short bar electrode, for sensing the level of non-aggressive electrically conductive liquids (water, water solutions). Electrode insulation from PP material, assembly into a sidewall of a vessel, or a pipe. Electrode length of 30 mm.
  • CLS–23_–12 Fully coated short bar electrode, for sensing the level of electrically conductive liquids (various chemicals, moderately aggressive water solutions). Higher temperature resistance compared to the variant “11”. Electrode insulation from FEP material. Assembly into a sidewall of a vessel or a pipe. Electrode length of 30 mm.
  • CLS–23_–20 Partially coated rod electrode, for sensing the level of electrically conductive and non-conductive liquids, partially resistant against fume condensation in the sensed area. Electrode insulation from FEP material. Installation from above, on shorter electrodes (max. 200 mm) also from the side. Electrode length from 50 mm to 1 m.
  • CLS–23_–21 Fully coated rod electrode, universal use, for sensing the level of electrically conductive liquids. Resistant against fume condensation and partially resistant against spraying media. Electrode insulation from FEP material. Installation from above, on shorter electrodes (max. 200 mm) also from the side. Electrode length from 50 mm to 1 m.
  • CLS–23_–30 Dismountable uncoated rod electrode, for sensing the level of conductive or non-conductive liquids. Installation
    from above, on shorter electrodes (max. 200 mm) also from the side. Electrode length from 50 mm to 1 m.
