Introduction to Multisensor Measurement SystemsMultisensor measurement systems integrate multiple sensor technologies to enhance manufacturing productivity. These systems utilize both contact and noncontact sensors to collect data points from parts for measurement purposes. Contact sensors, like CMM touch probes, physically interact with parts, while noncontact sensors, such as cameras and
laser scanners, gather data without direct contact.
Types of SensorsThe primary sensors used in multisensor systems include touch probes, video, and laser sensors. Touch probes are typically used in CMMs for point-to-point data collection. Video sensors capture images for measurement, while laser sensors use light to scan surfaces. Advanced microprobing technologies, such as resonant and spectral analysis microprobes, are also employed for detailed measurements.
Sensor Usage and Data CollectionSensors can be used for single-point data collection or continuous scanning. Touch-trigger probes collect data at specific points, while scanning probes maintain contact with the surface to gather continuous data. Video measuring machines can create 3D contour maps by scanning parts, and laser scanners continuously collect data points across surfaces.
Benefits of Multisensor SystemsMultisensor systems offer significant time savings and improved measurement capabilities. They allow for the automation of measurement routines, accommodating complex products and varying part features. These systems are particularly beneficial for measuring complex dimensional forms and surface relationships that single-sensor systems cannot handle.
Choosing a Multisensor SystemWhen selecting a multisensor system, consider the integration of sensors within the system's software and the ease of sensor changes during measurement routines. True multisensor systems optimize the performance of all sensors, unlike systems that merely add additional sensors to a primary one.
ConclusionMultisensor measurement systems are akin to multifunction office machines, offering space-saving, utility reduction, and streamlined training and service requirements. They are essential tools for achieving productivity improvements and cost reductions in manufacturing.
