MagnetoPot Potentiometers
As a level sensor, both liquid level sensor and a magnetic potentiometer, the MagnetoPot will give linear feedback to position. For liquid level sensors, 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 away from the activity.
Hydraulic and Pneumatic cylinders typically have only end Reed Switches to control over-extension, but the MagnetoPot can offer much more than the end Reed Switches; it can give full-travel position sensing with magnetic forces through a potentiometer output.
How it works
he 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.
Electrical Output
Just as with the traditional membrane potentiometer, the MagnetoPot gives a linear position feedback with the motion of the external magnet.
Res.-Tol. – ±20%
Lin.-Tol. – ±5%
Resolution: depends upon the exterior magnet strength and distance to the MagnetoPot
Internal Drive Magnet
The Spectra Symbol MagnetoPot uses a N42SH grade, Neodymium, magnet as the tracking magnet of the sensor. Spectra Symbol has partnered with K&J Magnetics.
