Configuration
3.4.7 Transducer blocks
The transducer block allows the user to view and manage the channel information. There is one
transducer block for the eight sensors that contains specific temperature measurement data,
including:
Sensor Type
Engineering Units
Damping
Temperature Compensation
Diagnostics
Transducer block channel definitions
The 848T supports multiple sensor inputs. Each input has a channel assigned to it allowing an AI
or MAI Function Blocks to be linked to that input. The channels for the 848T are as follows:
Off Spec Sensor 4 Degraded Confirm the operating range of Sensor 4 and/or verify the
sensor connection and device environment.
Off Spec Sensor 5 Degraded Confirm the operating range of Sensor 5 and/or verify the
sensor connection and device environment.
Off Spec Sensor 6 Degraded Confirm the operating range of Sensor 6 and/or verify the
sensor connection and device environment.
Off Spec Sensor 7 Degraded Confirm the operating range of Sensor 7 and/or verify the
sensor connection and device environment.
Off Spec Sensor 8 Degraded Confirm the operating range of Sensor 8 and/or verify the
sensor connection and device environment.
Maintenance Excessive Deviation Verify the process temperature, sensor wiring, and check
sensor integrity.
Maintenance Excessive Rate of
Change
Verify sensor wiring is appropriate in each junction point and
check sensor integrity
Check Check Transducer block under maintenance
