Direct load position sensing with secondary feedback encoders

Motion control system designers have found a way to eliminate or reduce common sources of position error, such as mechanical backlash, non-linearity, and hysteresis.  The method is called direct load position sensing and it employs linear encoders as a source of … Continue reading

Linear Position Sensor Terminology

Hysteresis, resolution, repeatability, non-linearity, null-point, temperature coefficient, accuracy.  These are but a handful of the many terms associated with linear position sensors.  To the uninitiated, it can be rather daunting.  And, unfortunately, there is a lot of room for ambiguity … Continue reading

What is the hysteresis of your magnetic field sensor?

I received a call the other day from a customer who wanted to use a magnetic field sensor on a cylinder, and evidently was requiring very precise results. His aksed “what is the hysteresis of your sensors? I notice that it is listed in your catalog as a percentage and I need to know the exact value in millimeters.” My response was, “well it depends”, upon which he was not overly pleased. I then continued to explain my answer which leads me to the contents of this posting. Continue reading
