Aim Motorcycle Suspension Potentiometer Rose Joint


Brand Aim

The Aim Motorcycle Suspension Potentiometer Rose Joint using Aim loggers can measure the displacement between two points using a sensor (linear potentiometer) directly connected to the points of measure. This potentiometer can measure linear displacements like:

  • dampers compression or extension

This is a good sensor to log when at the track. As, the Engineers can check to see how the suspension is performing when out on track. From this you can identify set-up changes such as, stiffen or loosen the suspension. This change could eliminate understeer or/ and oversteer.

  • steering rotation measured through the rack displacement


    When installing the sensor:

    • be very careful avoiding possible bending of the internal cylinder; these bendings, occurring when over tightening the screws or in case of incorrect mounting, can seriously damage the sensor
    • extract the internal cylinder for about 5 mm (0.2 inches) from the sensor lower boundary position.
    • if you need to open the two pop joints use the black plastic clip ; images here above on the right show the clip closed on top and open on bottom. 

    Please note: do not use this sensor to measure distances beyond the potentiometer maximum travel. 
    The car/bike linear potentiometer can be connected to any analog channel of AiM loggers.

    Aim Potentiometer CarSoftware setup – Suspensions

    Once the potentiometer installed it is necessary to load it in the configuration of its logger and then calibrate/auto calibrate it. 
    4.1 Setup with

    Race Studio 3

    To load the potentiometer in the logger configuration run the software and select the configuration you are going to load it on.

    Setup with Race Studio 3 Enter the configuration (in the example MXL2 03) and the related "Channels" layer.

    • Select the channel where to set the potentiometer on – in the example channel 6 (1) and fill in the panel that shows up
    • Function: "Position" (2)
    • Sensor: "Position Pot. AutoCal" (3 – this implies that the potentiometer will be auto-calibrated as shown in the following pages)
    • Fill in the other fields
    • Fill "Total Potentiometer travel" box with the potentiometer travel in mm – in the example we used a 75 mm travel potentiometer (4)
    • Click "Save"

    To auto-calibrate the potentiometer:

    •  enter "All" layer and press "Device" (1)
    • select the logger – in the example MXL2 ID 410 (2)
    • in "Live Measures" layer, keeping the potentiometer in its zero position, select the channel where the potentiometer has been set – in the example channel 6 (3)
    • press "Auto Calibrate" (4)

    • Keep the potentiometer in its zero position as shown here below
    • Press "Auto calibrate All". 

    • Keep the potentiometer in its zero position as shown here below • Press "Auto calibrate All".
