Membrane Potentiometer Technology: Improving On Traditional Potentiometers
When an engineer says, “linear potentiometer,” what do you think? A century-old technology, a contact wiper sensor that eventually wears out, a sensor that provides only analog output. These things are true. However, Spectra Symbol developed the Membrane Potentiometer to answer some critical questions in the design community on the usability of the potentiometer.
The key principle of the Membrane Potentiometer is the “membrane”, wherein the traditional wiper becomes obsolete. This is accomplished by building a top layer membrane over the top of the conductive element, which then acts as a sealed layer and wiper at the same time. Suddenly, the traditional linear potentiometer became a thin, elegant solution that could fit almost anywhere and had an IP rating of 65 against dust or water.
The longevity and stability of the Membrane Potentiometer increased dramatically over the traditional model, allowing for over 10 million cycles for the HotPot brand.High vibration applications make sense for this technology also, as the “dithering” with motion or large G jolts doesn’t impact the wiper system, or give error readings. Two examples are aerospace and automotive.
Recently, the R&D team at Spectra Symbol has developed the DigitalPot, which converts the potentiometer’s analog signal to Digital. This A-D transition offers OEM’s many options, from 8-bit to 16-bit processing for tighter stepped and pre-calibrated linear output. This allows for absolute linearity and the attendant distance measurement benefits.
Spectra Symbol’s membrane potentiometer has given linear potentiometer technology much needed innovation and usability.

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.

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.
