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 in any environment and enables the detector to distinguish between dangerous sparks and harmless ambient light.
IDT® enables adjustable sensitivity for hot particle detection in high-temperature processes and is also used to prevent false alarms.
Typical applications include pneumatic conveyor pipes, near inspection hatches, drop chutes and mechanical conveyors. The detector can be connected to every GreCon TOUCH control console using a standard three-core cable. A range of flexible mounting adapter options exist to suit any environment. The control console interfaces with the detector for monitoring of ignition sources within the process, the configuration of detection parameters and automated check of the detector optics' correct function.
Highly sensitive detector for detecting sparks and hot particles. Insensitive to daylight and artificial light. Excellent detection performance for all ignition sources in any environment thanks to adaptive detection technology.

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.
