The DLD 1/9 is a highly sensitive spark, ember and hot particle detector for protection against fire and explosion in industrial processes. Intelligent Detection Technology IDT® provides optimal detection performance for all ignition sources.

SPARK DETECTOR GRECON DLD 1/9 & 1/9 AS
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
