DLS–27, Dinel Capacitive-level sensors

Capacitive level sensors DLS – 27 Dinel
Capacitive level sensors DLS – 27 Dinel

Capacitive level sensors DLS are designed for limit sensing of the level of liquid and bulk solids in tanks, sumps, tubes or, hoppers, silos, etc. The sensors are manufactured in several modifications of sensing electrodes (rod and rope). The electrodes can be given an insulating coating, a useful feature in case of adhesive, aggressive, or conductive media sensing. Rod electrodes are also available in a version with a reference tube for measuring fluids in tanks made from a non-conductive material.

Sensors are manufactured in the following configurations: N – for non-explosive areas, Xd – For use in flammable dust atmospheres;
Xi – Explosion-proof – intrinsically safe for hazardous (explosive) areas and XiM – Explosion-proof – intrinsically safe for use in
mines with methane or flammable dust presence danger (see technical specifications). There are high-temperature performance
NT, XiT, XiMT available, and various types of process connections (metric and pipe thread, jointless connection Tri-clamp).

Features

  • For limit level sensing of liquid, and bulk-solid and powder materials
  • Universal using (bulk solids, liquids, aggressive materials, petroleum products, etc.)
  • Direct mounting into various containers, silos, vessels, tanks, filling inlets, reservoirs, etc.
  • Sensitivity and hysteresis fluently adjustable
  • Output types NPN, PNP, NAMUR
  • Direct mounting into various containers, vessels, silos, tanks, filling inlets, reservoirs, etc.
  • Outputs NPN, PNP, NAMUR (for explosive areas)
  • Sensitivity and hysteresis fluently adjustable
  • Supply voltage 7 … 36 V DC (NAMUR 8 … 12 V DC)
  • The material of housing and electrode from stainless steel
  • Process coupling – thread M27x2; M30x1.5; G3/4“ or Triclamp
  • LED state indication
  • Xi, XiT versions for usage in explosive areas, or Xd version for usage inflammable dust areas, or XiM, XiMT versions for mining environments with a risk of hazard by methane or coal dus
