Critical factors come into play when selecting a displacement sensor and other precision measuring instruments
Despite their frequent use, terms such as accuracy, resolution, repeatability and linearity are often misunderstood.
“As critical factors in the selection of a displacement sensor, as well as in many other precision measuring instruments, engineers must ensure they fully understand the terminology before making a purchasing decision,” says MicroEpsilon.
Unfortunately, not all displacement sensor specifications are presented in a way that allows direct comparisons to be made. “The terminology applied to sensors can be confusing, but is critical when it comes to selecting the right measuring instruments for an application – especially for displacement and distance sensors," says the company.
"If engineers get this part wrong, they could end up paying more than they need to for over-specified sensors.
"Conversely, a control system or product may lack critical performance, if the displacement sensor does not meet the required specification.”
MicroEpsilon has put together a White Paper on the topic, which can be accessed here.
