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.
