5.6 Configuring Input Parameters for RTD and Thermocouple
Input Types
5.6.1 Applying a Bias to the Temperature Input
When using an RTD or thermocouple input, you can specify the bias (if any) to be applied
to the input. Applying bias allows you to compensate for any difference between
sensor reading and the point to be measured. The displayed process variable and
setpoint will be offset by the value entered here. (You can leave the input bias set to the
default zero when setting up the controller. If the need for bias becomes evident later,
you can adjust the configured value.)
Parameter Name
: Input Bias (86)
Name as Displayed:
bIASbIAS
Used By:
all controllers
When Displayed:
always
Range:
–1000 to 1000 °F
–556 to 556 °C and °K
Default:
0
Description:
Applying bias allows you to compensate for any difference (plus
or minus) between sensor reading and the location to be
measured. The displayed process variable and setpoint will be
offset by the value entered here.
Effect on Other
Parameters:
No effect on other configuration parameters. However, the bias
will be applied to the displayed PV and the active setpoint.
