Www.Interlinkelectronics.Com 1 force sensing linear potentiometer (fslp) integration guide 1.0 introduction the interlink electronics standard force sensing linear potentiometer (fslp) is a linear position sensor for menu navigation and control. It functions as a linear potentiometer with the abilit...
Www.Interlinkelectronics.Com 2 force sensing linear potentiometer (fslp) integration guide 3.0 theory of operation the most basic force sensing resistor (fsr) consists of two membranes separated by a thin air gap. The air gap is maintained by a spacer around the edges and by the rigidity of the two ...
Www.Interlinkelectronics.Com 3 force sensing linear potentiometer (fslp) integration guide like the basic single-zone fsr, the interlink electronics fslp has an fsr ink layer and a conductor substrate layer separated by an adhesive spacer. The fslp’s conductor layer however, is not simply a set of i...
Www.Interlinkelectronics.Com 4 force sensing linear potentiometer (fslp) integration guide figure 3 shows a schematic view of the sensor. Notice that the sensor is a three-terminal device and when touched, has a circuit that is equivalent to three resistors. R1 is the resistance from sensor terminal...
