How Does it Work?

A Sensofoil® membrane potentiometer PET-Hybrid consists of a resistive track printed the bottom PET foil layer and a collector track printed onto the top PET foil layer. These layers are seperated by a so-called spacer. Only when the layers connect through mechanical pressure using a wiper a signal is produced.

The special feature of the Hybrid version is the additionally integrated flexible metal strip, ensuring that the upper foil always returns to its original form after being exposed to long lasting pressure at high temperatures. This integrated Hybrid technology provides broader application possibilities due to the increased operating temperature range.

Ideally, a low DC voltage is connected to the resistive track and tapped at the collector track in the form of a voltage divider. A linear relation exists between the length of the resistive track, or the angle of the resistive track for rotary sensors, and the applied voltage. At 50% of distance traveled, 50% of the applied voltage is measured.

Quality characteristics of the Sensofoil® membrane potentiometers are resistance values, their corresponding tolerances and the non-linearity. The non-linearity represents the actual deviation of the output signal to an ideal reference line and is expressed as a percentage of the applied supply voltage.
