The HotSpotIR is an infrared scanning system designed to detect emerging hot spots on moving conveyor belts by continuously measuring temperature across the full belt width at up to 100 Hz. It features a fixed focus of 1200 mm with a 100:1 distance-to-spot ratio, a scan angle of 80°, and a measurement range configurable to 20-250 °C, 50-400 °C, or 100-600 °C depending on variant. The system includes a Class 2 laser alignment aid (1.0 mW, 635 nm), IP65 environmental sealing, and operates in ambient temperatures from 5 to 70 °C. It outputs temperature data and alarm signals directly to a control system via a dedicated processor. The device measures 206 x 209 x 100 mm and complies with EN 61320:1999 Class A and IEC 1010 safety standards. Hazloc versions with ATEX Zone 20 or 21 certification are available.
The transportation of coal on any form of conveyor system has the potential to ignite, with the ultimate outcome being a fire. Coal (even in small amounts) is a very good insulator, so fire which is burning beneath the surface may not be immediately obvious. A single point temperature measurement system can detect a hot spot, but is just as often likely to miss one.
Temperature Scanning - real benefits
A scanning temperature measurement system which looks at the entire width of the conveyor at any one time is an ideal solution. It scans at a wide angle (the entire conveyor width), at high speed and with a fast response. Every hot spot can be detected as all the coal surface is viewed. The scanner is capable of detecting even small hot objects on the conveyor, with its high-speed scanned detector. The scanner outputs the hottest temperature on the conveyor directly to a plant control system or suitable customer alarm system.
Simple Installation
The system is mounted above the conveyor and is connected via a single 8-core cable to the processor unit (usually mounted in a control room). The processor powers the scanner and also provides the signal outputs. The scanner is highly robust with a range of mounting and protection accessories.
Conveyor belts are expensive and replacements can carry long lead times - maximize your belt life and plant productivity by detecting hotspots before problems occur.
