Process Conditions

Field Communicator Configure > Manual Setup > Process Conditions (2-2-4)
Follow the prompts on the Field Communicator to view or edit process condition information.
D RTD Data is visible when Process Temperature Source is not Manual Entry.
Process Temperature displays the process temperature measured by a resistance temperature detector (RTD)
located in the process fluid.
RTD Wire Resistance displays the user estimate of wiring resistance (per lead) when employing a 2-wire RTD
connection.
D Temperature Setting is a menu item that only appears when Process Temperature Source is "Manual Entry".
If a process temperature sensor (RTD) is not installed, it is possible to manually set the Digital Process Temperature
variable to the target process temperature. This value will be used by any SG-compensation tables that the user has
entered. If no compensation tables are active, the Digital Process Temperature value may be used to document the
process temperature at which the instrument was calibrated, or the process temperature for which the stored
torque rate is pre-compensated.
The Process Temperature value may be edited directly in the Temperature Setting menu item. Press Enter and then
Send to load the new value to the device.
D Process Temperature Source allows you to select the source of the process temperature parameter; Manual or
100 ohm platinum 2-wire or 3-wire RTD.
D Change Source allows you to configure an RTD to measure process temperature, or manually enter a process
temperature value to be used for Primary Variable compensation.
When configuring an RTD you must select the number of wires for an RTD; either 2 or 3.
For a 2‐wire RTD, you must specify the connecting wire resistance for one wire of the pair. If you know the
resistance, select Resistance and enter the resistance of the wire. 250 feet of 16 AWG wire has a resistance of 1 ohm.
