                              Latest software boosts SensorX bone detection performance
           For poultry processors around the world, Marel’s SensorX set a new standard in bone detection when it was launched in
         2006. From then to now, Marel did not rest on its laurels but continued to improve the popular concept. Given the current
          great emphasis on food safety, SensorX’ strive for ultimate, bone-free product quality is perfectly placed. The latest im-
             provement implies the virtual elimination of false positives – normally a disruptive inf uence in bone detection.

                                            isn’t high enough. The first aim of Marel
                                            was therefore to achieve the highest per-
