This amazing XY tilt sensor is from FSG in Germany, it was installed in a crane many years ago,
I got this one from the last hamradio fleamarked,
the sensors are inductive filled with vibration dampen oli,
the inductive system runs at 12kHz time pulse difference is converted to 4-20mA outputs using two TLC27M4 opamps,
it is super accurate and stable and still works after 30 years !!
this reveal top quality product, but ok it is not a cheap toy but high end pro.
Price in 1994 was 675 Euro, Price in 2024 is 1240 Euro.
Huge thanks to all my German friends for the help with documentation.
