it works on the principle of electro-magnetic flux

Answer / nileshkumar jambukiya

non contact type vibration sensor is work on eddy current
prenciple, when gab between object and sensor is increse
then more eddy curent drown so this current convet into
voltage in its transducer so maximum volage out put get
and vice versa minimum gap between object and sensor.

dynamic state of an object

I have a problem with a valve (air to close). When it is fully closed and try to open 1% it doesn't responce till 3% open suddenly more than 3% then back to 3%. I tried to tune positioner then removed it, the problem still exist. Any idea

I work on a electronic positioner transmitter 4211 at the field.I connect my multimeter in series to get the current output then I calibrate it to 4ma in 0% of position of the valve and 20ma in 100% position of the valve.My problem is in the field I get the correct output current based on my multimeter but in the dcs they only receive 40% in a output 20ma of this positioner.Then I try to simulate in this analog card and they receive the equivalent percent on the value that I simulated.Is ther any possibility to reset the zero and span of this positioner 4211 fisher.And what other possibility I can do to fixed this.This is my email add ( landicho_randy@yahoo.com )
