Spark De­tec­tor Gre­Con DLD 1/9 & DLD 1/9 AS

For the best detection performance in any environment

Home Industrial Fire Protection Components Spark Detector DLD 1/9 & DLD 1/9 AS

Key benefits

  • Highly sensitive spark detection of sparks, embers and hot particles in processes up to 150°C
  • Detection not dependent on temperature of ignition source
  • Highly reliable Intelligent Detection Technology IDT® adapts to any environment
  • Flush-mounted installation of detector optics for maximum life
  • VdS approved, and also available with dust explosion protection certifications (ATEX and IECEx)

Functional description

The DLD 1/9 spark detector offers optimal detection performance for all ignition sources in any environment thanks to Intelligent Detection Technology (IDT®). Two versions are available depending on the application conditions:

  • The classic DLD 1/9 is ideal for areas without ambient light.
  • The DLD 1/9 AS is recommended for applications exposed to ambient light.

Both versions are highly sensitive spark detectors with numerous advantages. They reliably distinguish between dangerous sparks and harmless ambient light, preventing false alarms and enabling the detection of hot, non-glowing particles in high-temperature processes. Additionally, the sensitivity is adjustable, allowing precise adaptation to individual risk levels.

The DLD 1/9 can be used in pneumatic conveyor pipelines (including near inspection hatches), drop chutes, and mechanical conveyors. It connects to any GreCon spark detection control panel with a touchscreen display via a simple three-core cable. All GreCon control panels continuously monitor this connection for faults and automatically check the detector’s functionality at programmable intervals.

Air purge adapter
If dirt accumulation or other build-up on the sensor optics is expected, special air purge adapters increase the detection reliability. Cleaning intervals are thus extended.
