EHELP: Is There a Solution to Pass Hart Data Through an Isolator to My DCS?

EHELP: Is There a Solution to Pass Hart Data Through an Isolator to My DCS?
Q. I want to share a critical pressure signal with my DCS that is now part of our safety instrumented system (SIS) and have a two part question. First, do your isolators pass the HART diagnostic data that comes from my SIS smart pressure transmitter? Second, if there is a total failure of the pressure transmitter, where will the output of the isolator go to that is feeding my DCS?

EHELP: How do I account for the linearization function representing the volume measurement in a cone-shaped bottom tank at various levels?

EHELP: How do I account for the linearization function representing the volume measurement in a cone-shaped bottom tank at various levels?

Q.  We want to use a SPD Field-Mount Programmable Loop Display with a radar transmitter mounted on the top of a cone-shaped bottom tank that outputs 4-20mA signal, and we would like to know how to account for the linearization function representing the volume measurement in the tank at various levels?

EHELP: Can the ECT-DIN, be configured for a 4-20mA input and 4-12mA split range output?

EHELP: Can the ECT-DIN, be configured for a 4-20mA input and 4-12mA split range output?

Q. Can the ECT-DIN, configured for 4-20mA input and 4-20mA output, be calibrated to give 4-12mA output when the input is 4-20mA so that the output is 1/2 the input? We have a radio I/O signal that is scaled to 4-20mA for 0-65, 535raw units. When sent to the PLC over Modbus, it can't be read properly since the maximum register value size for the PLC is limited to 32767.
