The importance of choosing the right filter to suit your measurement application

When selecting sensors for displacement, position, distance and profile measurement tasks, engineers should consider the various types of sensor filtering before making a purchasing decision, says Chris Jones of Micro-Epsilon. The quality and reliability of an output signal from a sensor is often affected by external or environmental factors (e.g. …
