They have many names, Linear Potentiometers, Linear Pots, Linear position sensors but in essence they are one of the most common forms of measuring device for linear position. They are incredibly simple to use relative to other devices, infinite resolution, output is proportional to stroke length and very robust.
Not all Linear pots are the same. Ours have unique features to ensure long trouble free life in the most harsh of environments from motorsport to structural monitoring. From measuring linear position or displacement in a wide variety and broad range of manufacturing and process equipments.
Options include 4-20mA output, front or rear facing cable exits, Ingress protection IP65/67, spring return versions, rod ends or pop flanges.
