More and more companies are offering multisensor measurement systems, yet most of the available information about such systems is with regard to sensor technologies. Although it is helpful to know how different sensors work, it is more important is know how to make use of more than one sensor to improve manufacturing productivity.
- All measurement systems use at least one type of sensor technology.
- The sensor collects data points from a part to obtain a measurement.
- Data points can be collected by numerous sensor technologies such as a touch probe, video, laser and microprobes.
What is it?
There may be some confusion about what a multisensor measurement system actually is. All measurement systems use at least one type of sensor technology. The sensor collects data points from a part to obtain a measurement. It is the probe, or detector, that “senses” the part.
Sensor technologies can be grouped in two major categories—contact and non-contact. Contact sensors are those that apply any pressure to a part to obtain a measurement. Coordinate measuring machine (CMM) touch probes are the most common type of contact sensors.
