The MagnetoPot is simple, yet elegant in its ability to track motion in a contactless manner. A magnet on the
inside of a cylinder, or a magnet on the opposing side of a motion device will guide the built-in magnetics of the
MagnetoPot for position location through a potentiometric output.
The MagnetoPot is a sealed potentiometer, in the membrane potentiometer tradition, yet it does not require a
wiper/actuator to connect the collector and the resistor. Instead, the MagnetoPot is controlled by an outside
magnet, which attracts the magnetic forces within the MagnetoPot to connect to the linear resistor and give linear
potentiometer feedback.
The wiper inside the sealed pot is magnetic or ferromagnetic, and will only perform if connected with an exterior
magnet.
As opposed to a magnetically-based Reed Switch, which gives simply “open” or “close” signals, the MagnetoPot
gives the full linear travel of a hydraulic or pneumatic cylinder.
In liquid level applications, the MagnetoPot can attach to the outside of a liquid tank and give position of the
magnet inside the float. No water ingress, no wearing of the part by environment, because the MagnetoPot is
outside of the tank.
The MagnetoPot is made of polyester, fiberglass and kapton, depending on the specification required. It functions
as a voltage divider, a resistor or rheostat, as desired by the end-user. By bringing the exterior magnet into a
proximity necessary to connect with the internal magnetic attractors, the operator can obtain linear position
sensing based on the location of the exterior magnet. As the exterior magnet moves, so does the electrical output
of the MagnetoPot.
The MagnetoPot should not be mounted to a ferromagnetic surface.
