Question
Electrical Signal
On a garage floor a small limestone block 150 mm by 50 mm by 20 mm on a fixed roller support
XXXXXXXXXXXXXA
F R
Sensor at A, the F and R are small wooden blocks and a roller.
I pick up the electrical signal to 420 Hz.
The limestone is vibrating at 460 Hz quite nicely as it is a heavily degraded block so the Sensor TileBox Pro is quite good, but should I normally see electrical signals this high, the CX1 stops at about 180.
