inbuilt zener barriers? why

Answer Posted / amit patil

YES ALL INTYRENSIC SAFE TRANSMITTERS R BOUNDED WITH ZENSER
BARRIERS BECAUSE THESE R HAZARDOUS SIGNALS COMMING FROM THE
FIELD, SO TO AVOID ANY DANGEROUS EFFECT TOWARDS THE PANNEL
SIDE BARRIERS R USED THESE R SO THAT IF MORE CURRENT IS
COMMING FROM YHE FIELD THEN THE BARRIER BECOMES OPENE TO B
SAFE FOR PANEL SIDE.

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.
