Operating menu and parameter description iTEMP TMT82
74 Endress+Hauser
Drift/difference alarm delay
Navigation Setup → Advanced setup → Sensor → Drift/difference alarm delay
Expert → Sensor → Diagnostic settings → Drift/difference alarm delay
Prerequisite The Drift/difference mode parameter must be activated with the Out band (drift) or In
band option. → 73
Description Alarm delay for drift detection monitoring.
Useful for example in the event of different thermal mass ratings for the sensors in
conjunction with a high temperature gradient in the process.
User entry 0 to 255 s
Factory setting 0 s
Drift/difference set point
Navigation Setup → Advanced setup → Sensor → Drift/difference set point
Expert → Sensor → Diagnostic settings → Drift/difference set point
Prerequisite The Drift/difference mode parameter must be activated with the Out band (drift) or In
band option.
Description Use this function to configure the maximum permissible measured value deviation
between sensor 1 and sensor 2 which results in drift/difference detection.
Options 0.1 to 999.0 K (0.18 to 1 798.2 °F)
Factory setting 999.0
Sensor switch set point
Navigation Setup → Advanced setup → Sensor → Sensor switch set point
Expert → Sensor → Diagnostic settings → Sensor switch set point
Description Use this function to set the threshold value for sensor switching.→ 69
Additional information The threshold value is relevant if the sensor switching function is assigned to a HART
®
variable (PV, SV, TV, QV).
Options Depends on the sensor types selected.
Factory setting 850 °C
