Hot Slug Detector
Hot slugs form in the fiber batting process when molten glass falls from the spinner and into the product. Surrounded by insulating material, these hot slugs remain hot, and days later can cause the paper backing and organic binder material to ignite, creating a fire in a warehouse, on a train or in a truck.
Williamson’s Hot Slug Detector (HSD) combines three innovative pyrometer technologies to identify small slugs below the fiberglass batting’s surface.
OVERVIEW
Short-Wavelength Technology
- Short Wavelengths view deep into the batting to sense even the smallest hot slug.
- Model HSD-00 views as deep as 16 inches into the batting and is compatible with conventional lighting.
- Model HSD-01 views as deep as 30 inches into the batting and is compatible with LED lighting, fluorescent lighting, or an area in a shadow. This model is more than 3 times more sensitive to hot slugs near the bottom of the batting compared to the model HSD-00.
Unique Hot Spot Detection System
- The Rate of Change (ROC) alarm system senses the small but instantaneous change in temperature reading associated with the introduction of the hot slug into the field-of-view.
- The ROC compares the current reading with the reading taken a fraction of a second earlier. Any rise in temperature is amplified and the result is used as the hot slug alarm parameter.
