PROLINE - TYPE IH-153E EMBER DETECTOR
Description
The IP67 rated model IH-153E Ember Detector employs Infra-red sensitive photoelectric sensors for the detection of glowing embers on applications such as COAL CONVEYORS. The unit has a narrow spectral sensitivity ( 3 to 5 um) making it impervious to visible light. The detector can reliably and rapidly detect weak Infra-Red radiation emissions from embers resulting from smouldering fragments of wood or coal. The sensitivity of the IH-153E, being designed and constructed specifically for the detection of glowing embers, is far superior to more conventional flame detectors. With Instrument air air purging at 3 to 7 bar used to keep the detector eye clean in polluted environments.
The IH-153E will detect 100 sq cms glowing ember at a distance of 1 to 3 metres in a 90 degree cone angle and straight line.
Connection of the IH-153E to any standard Fire Alarm Control Panel, annunciator, PLC, DCS is by way of the potential free NO/NC contacts provided. Operating Status indication of the detector is by LEDs (flickering green = normal condition, static red = alarm).
Applications:
Highly recommended for use on coal conveyors to detect smouldering coal or glowing embers on a moving belt.
Any Material transportation system where glowing embers may present a risk of fires.
Environments that are unsuitable for other types of detectors to be installed and operate with a moving ember or small flame fire risk
Detector Sensitivity:
100 sq cms at a distance of 1 to 3 metres in a 90 degree cone angle and straight line.
Advantages:
Rugged construction for use in challenging environments
High Sensitivity even in Mist and Fog
Easy to instal and operate
High speed response
Free from false alarms
Visual operating status indication
Low maintenance
Installation Considerations:
The fladet IH-153E detector must be installed ensuring there is no obstruction in its line of sight.
Other IR radiation sources (sunlight or hot bodies) may adverselt affect detector performance
For conveyor applications, detector mounting should be on the hood or gantry of the conveyor structure with detector line of sight along (not across) the conveyor belt.
Maintenance & Inspection:
For maximum sensitivity, the surface of the detector tube should be kept free from dirt or other contaminants at all times. Periodic testing of the detector using controlled embers-should be carried out.
An additional provision exists for connection to a pneumatic air purging system to keep the detector surface clean.
