Infrared Sensors (HMD) in Protection Tube
For installation in the roller conveyor, between the rollers.
Infrared sensors (Hot Metal Detectors) in high temperature protection tube can be integrated into the roller conveyor under the material, and are ideal when mounting above the rollers is not possible due to the plant structure or because of moving cranes.
A detection position quite near the hot material ensures accurate switching and reliable operation. The protection tubes are available in different lengths, with one, two or three optics, to meet the different application requirements, and also to offer different combinations for redundant control. Thanks to their integrated air purge and an extremely robust and maintenancefree construction, they feature trouble-free operation also with high material temperatures and heavy dirt formation.
The protection tube can be inserted from the side into the conveyor; this mounting method makes service or replacement possible also during operation - no need for plant shutdown. Belonging to the OX series, they can be parameterized in a teaching mode and offer the possibility to set different behaviors for multiple outputs, as well as an offset function with different response and switch-off temperatures, or an alarm function.
These sensors are equipped with a comfortable software interface to meet the needs of Industry 4.0.
Application areas
- Detection of hot objects
- Material tracking on roller conveyors
- Control of slabs, blocks and billets position at continuous casting
- Material control during hot rolling
- Activation of conveyors in hot areas
