Historically modern machines have used in industrial automation have employed many different electromechanical encoder technologies to for their basic essential navigation and positioning information. These types of sensors included rotation and linear encoders, RF tags, accelerometers, inclinometers, fluxgate compasses, speedometers, resolvers, laser ranging etc. to simply name a few. Depending on specific component quality levels, all these sensors technologies work reasonable well, although, each do have unique vulnerabilities that affect their reliability and accuracy from time to time.
However, are these old positioning technologies reliable enough alone to underpin modern safety & integrity for mission critical machine optimisation projects..? (We don’t think so..!)
