why we set -10 volt in vibration sensor output,why not +10 volt ..

Answer / piyush vyas

hello dear ,
well u can use -10 volt ,bt main reasion is tha because of we using the i/p supply is -24 and its reasion is that we are using in that pnp and pnp bias is always negative ,we can use
positive npn ,bt the bently had modulded in negative ,so we are set to on -10 volt.

Answer / r.murugan

Vibration sensor output based on your probe gap
normal refrence from shaft and probe gap +1.2mm

corrosponding +1.2mm gap you will get output of the
proximitor -10v

if gap is increase voltage will increase gap is decrease
voltage will decrease

bently vibration probe calibration there is kit TK3-2E

PROXIMITOR POWER SUPPLY VOLTAGE -24V DC (THIS ONE PNP
FUNCTION BASE)
