Customer requests:

A shredding facility operates unmanned for an extended period and has known risks for starting a fire: Heat, fuel sources and oxygen. The friction of the scrap generates heat that, together with oxygen, can ignite existing flammable liquids like fuels, oils, and grease, as well as materials such as paper and cardboard.

In unguarded facilities, a fire can spread significantly before detection. Metal shredding plants are often located in less fortified production halls and increased risk of personal injury and machine damage.

Solution with Optris infrared cameras

Optris offers the solution with IR cameras of the Xi/ PI series: increased temperatures in shredders, which can lead to a fire, are detected early, and a reliable alarm avoids dangerous situations.

For example, the latest solution from Optris, the compact IR camera Xi 410, works fully autonomously. In an alarm situation, the sensor independently sends signals to process instances that can, for example, shut down the motor or disconnect the power supply to affected shredders.

• Optical resolution: 384 x 240 pixels
• Spectral range: 8 to 14 µm
• Temperature range: -20°C bis 900°C
• Spot to distance ratio (D:S): 390:1 (18° optics) 
• Motorised focus
• Thermal sensitivity: (NETD) 80 mK
• System accuracy (at ambient temperature 23 ±5 °C): ±2 °C or ±2 %, the larger value applies
• Ambient temperature(TUmg): 0 °C to 50 °C

Other advantages of the Optris Xi410 are its features, such as motor focus and integrated auto hotspot finder, making rugged and compact imagers like the Xi 410 ideal for safety-related applications, especially in the area of preventive fire protection and condition monitoring of machinery and equipment. The optical components of the infrared cameras can also be kept clean effectively in harsh environments by using air purge sleeves.
