Thanks in advance as he's a bit stuck on an assignment!!!

how to calibrate a Damper Position Sensor or Linear Potentiometer on a Damper please?

Thanks chaps!

He'd need to be able to move the damper to each extreme end of travel, and measure the output from the linear pot. Measure the height at each extreme. It's just a bit of maths to calculate the damper extension, once you know these four values. Practically, you'd probably need to do this without the spring fitted. Does that help?

A linear potentiometer will give out a voltage proportional to position. Assuming the linear pot is aligned to measure along the linear stroke of the damper, he'll need to measure the voltage at both the minimum and maximum stroke positions (fully compressed, and fully extended), then measure the distance of full travel of the damper. Once he's got these 3 values (Vmin, Vmax, and stroke distance) he'll be able to get the calibration figure in V/mm. Hope that helps...?

Is this really what education has come to - getting your Dad to do your homework via internet forums?

He's just asking for help in one part of it, as above, much like asking a friend.

Thanks for the help folks thumbup
