7.6. TORQUE TUBE TEMPERATURE COMPENSATION
7.6.1. G
LOBAL PURPOSE
The 12400 Series instrument includes a non-intrusive and integrated software temperature compensation of the torque tube
from -210°C to +450°C.
There are two temperature sensors located in the sensor board and the main circuit board of the instrument.
Variation of torque tube Young modules over ambient and process temperatures shall be compensated to prevent any zero shift
and span variation on very high or low process temperature applications.
The software module compensates these potential variations of Young modules that may happen in case of temperature
difference between temperature saved during calibration procedure and current temperature (impacted by ambient and
process temperatures).
This function is available on device revision Firmware 114 or later.
ValVue suite software is required to set this temperature compensation feature. Push-buttons and any HART handheld do not
enable to activate and set this feature.
