Answer Posted / smart dude
in vibration senseor we give -24 v in proximitor becoz it
have vaild reason
and reason is that becoz we have to take o/p of proximitor
is -10 to 0
and why we have to take the voltage o/p -10 to 0 is that
becoz and the distance b/w shaft and and sensor get less rf
signal is absobed by the meatal and voltage gets
down ,,,but acc to human mind setup as gap decrease singla
amount shoukld increase (as in case of 4 to 20 ma ),so we -
ve volatage o/p becoz as -ve voltage decrease it means vale
is increasing (acc. to math -4<-3)
