2.7.4
Sensor Drift Alert configuration
The Sensor Drift Alert command allows the transmitter to set a warning flag (through HART), or go into
analog alarm when the temperature difference between Sensor 1 and Sensor 2 exceeds a user-defined
limit.
This feature is useful when measuring the same process temperature with two sensors, ideally when
using a dual-element sensor. When Sensor Drift Alert mode is enabled, the user sets the maximum
allowable difference, in engineering units, between Sensor 1 and Sensor 2. If this maximum difference is
exceeded, a Sensor Drift Alert warning flag will be set.
