An extremely compact, fast-response infrared scanning system designed to detect emerging hot spots on conveyor belt materials.


Designed for industrial environments, the fixed-focus HotSpotIR high-speed scanning system detects small hot inclusions on a moving conveyor before they can cause a fire. Reliable alarm processing is achieved without software or computer requirements. HotSpotIR rapidly identifies small, hot particles on a moving conveyor, preventing damage and costly shutdowns. Its high resolution and fast scan speed allow it to detect hot particles as small as 25 mm (1 inch) across.

Connecting to a dedicated processor, the scanner can measure up to an entire belt surface. If any part of the surface is above a user-set limit, it activates an alarm which can be set to trigger fire suppression systems.  HotSpotIR is suitable for ensuring the safe transport and storage of materials in the hydrocarbon processingindustrial processingpower generationsteel and cement industries, with an optional version available for use in hazardous environments.

With high-resolution monitoring across 1000 temperature spots, user-adjustable scanning speed up to 100 Hz, and a repeatability of ±0.5 °C (0.9 °F), HotSpotIR protects the entire conveyor belt against hot spots as small as 25 mm (1 inch) across.

Continuous, accurate and fast monitoring means hot spots are detected and an alarm triggered in a hundredth of a second, allowing the plant operator to respond quickly to a potentially-dangerous condition. That means safer employees, reduced damage and downtime risks, and lower insurance costs.

HotSpotIR is small enough to be positioned under a belt just after material transfer, allowing it to monitor the entire belt surface. It can also be placed above the conveyor to find hot spots in the material before loading.

HotSpotIR is AMETEK Land’s compact, accurate scanner for conveyor belt systems.
