GRECON DLD 1/8 A ID:581591 SPARK DETECTOR

GRECON DLD 1/8 A ID:581591 Spark Detector is used in GreCon's fire prevention and extinguishing systems, specifically for detecting sparks, glowing embers, and even hot, non-glowing particles in environments with ambient daylight or artificial light. Its "DLD" (Daylight Detector) feature makes this detector ideal for situations where other standard infrared detectors might trigger false alarms due to light ingress (e.g., in transparent pipes, open conveyor belts, or near inspection hatches). Primary areas of use include systems where flammable materials are processed or conveyed, such as woodworking industries, textile industries, recycling facilities, food processing plants, and paper manufacturing. It is vital for early detection of ignition sources that could cause fire or explosion, especially in locations like conveyor belts, open chutes, drop chutes, and pneumatic conveying ducts with high material loads.

GRECON DLD 1/8 A ID:581591 Spark Detector is a highly sensitive spark and hot particle detector with advanced infrared technology. Unlike some other detectors, this model is insensitive to daylight and artificial light, which allows it to operate reliably in illuminated environments. The detector uses a lead sulfide (PbS) sensor element as its detection principle and can detect not only sparks but also hot particles that do not glow in the visible range but still pose a danger. A detected spark or hot particle signal is transmitted to the connected GreCon control panel, which automatically activates extinguishing systems (e.g., water spray) or other safety measures (e.g., stopping the conveying line). Its robust construction ensures reliable operation even under harsh industrial conditions, including high temperatures within the material flow.
  • Model Number: 581591
  • Type: Funkenmelder (Spark Detector)
  • Series: DLD 1/8 A (Daylight Detector)
  • Detection Principle: Infrared (IR) - Typically using a lead sulfide (PbS) sensor element.
  • Detection Sensitivity: High, capable of detecting sparks as well as hot, non-glowing particles.
  • Insensitivity to Light: Insensitive to daylight and artificial light.
  • Spectral Sensitivity: Typically in the range of 1650 nm to 3500 nm (different from other FM series detectors).
  • Operating Ambient Temperature: Stable operation over a wide range (e.g., -40 °C to +60 °C).
  • Material Flow Temperature: Up to specific temperature limits within the material flow (e.g., ≤ 70 °C).
  • Transportation Speed: Typically 2 to 50 m/s (other speeds on demand).
  • Housing Material: Durable material (e.g., Macrolon or similar industrial plastic).
  • Protection Class: Typically IP65, protected against dust and water ingress.
  • Connection: Wired connection compatible with GreCon control panels.
  • Mounting: Flexible installation options with various mounting adapters.
  • Ex Protection: "Ex" versions of the DLD 1/8A (e.g., DLD 1/8A Ex) may have ATEX certifications for use in explosive atmospheres. If this model number ends with "A", its suitability for explosive environments should be verified separately.
