Dinel CLS–23 Capacitive Level Sensor

Dinel CLS–23 Capacitive Level Sensor 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.

Dinel CLS–23 Capacitive Level Sensor Benefit:

  • Detection of various types of electrically conductive or non-conductive liquids (water, water solution, cooling liquids, oil, etc.)
  • Sensitivity setting through 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
