14.3.8 Transducer Block "Advanced Diagnostic"

The "Advanced Diagnostic" Transducer Block is used to configure and display all the

diagnostic functions of the transmitter.
Functions such as
• Corrosion detection

• Drift detection

• Ambient temperature monitoring
are displayed here.

Corrosion monitoring

Sensor connection cable corrosion can lead to false measured value readings. Therefore

the unit offers the possibility of detecting corrosion before a measured value is affected.

Corrosion monitoring is only possible for RTDs with a 4-wire connection and

thermocouples (see also →  43).
Drift detection can be configured with the SENSOR_DRIFT_MONITORING parameter. Drift

detection can be enabled or disabled. If drift detection is enabled and a drift occurs, an

error or maintenance request is generated. A distinction is made between 2 specific modes

(SENSOR_ DRIFT_MODE). In the 'Overshooting' mode, a status message is generated if the

limit value (SENSOR_DRIFT_ALERT_VALUE) for the drift is overshot, or if the limit value

is undershot in the 'Undershooting' mode.
