The LBK Safety Radar System safeguards danger zones close to machinery and systems with radar technology. The system operates in a frequency range of 24 GHz. The compact sensors with their integrated antennas emit electromagnetic waves that are reflected off objects and harmless to personnel. The sensors receive these reflections and then evaluate them.
Even nonmetallic objects such as dust, welding sparks, and chips are penetrated without the sensor being influenced. The LBK therefore switches off reliably when a person is in the danger zone. The LBK sensor emits its radar waves in three-dimensional space so that not only the surface area, but also the volume of this space is monitored.
It also uses Frequency Modulated Continuous Wave (FMCW), an operating principle which is new to safety technology. Here, the transmission frequency changes within a defined bandwidth, meaning the LBK sensor can determine the speed at which the person is moving. The slight movements of a person are sufficient to generate a reliable switch off signal for the machine. As a result, the LBK system interrupts the operating process only if somebody is actually located inside the danger zone.
Users can adapt it to their individual requirements. The system consists of a controller to which up to six radar sensors can be connected. The positioning of the sensors, the adjustable operating range, and the selectable opening angle allow flexible adaptation of the monitored area to the danger zone.
