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 (

AI card is two wire and the electronic positioner
transmitter is also two wire. I already simulate ma directly
into the card and the DCS receive the equal percentage of
the ma that I simulated.

We Have Two Field bus Pressure Transmitters of Different Sensor Range (I.E One is of Lower range and Another is of Higher Range).Is same Process Line. My Question is Can i provide Saturation Limit to my field Bus Transmitter as We can provide Saturation current limit to HART Instruments. As During Low Pressure Both Working OK ,But During High Pressure, transmitter with Lower sensor range Goes to Fault mode as Beyond its Sensor Limit it can Measure, So may I provide Saturation point Some where to Suppress This Fault during High Pressure.

you must show the examples application and give at least 4 types of transducer/sensors that can minimize the failure during the manufacturing of the resistors.
