Further to my recent post about float switches to use in the header tank of a LN2 aircraft, Silvio kindly posted the response, below, on the List. These sensors appear to be very small, light and easy to install in the header tank. I was wondering whether anyone else on the List has used them, and if so, what your experience of them has been – good or bad.

Thanks again in anticipation.

There is an optical switch that works very well in my Lancair. You will need some electronics. Do not have PN but you can look at Google. See attached sheet.
