
The Sensor Limits and Minimum Span can be viewed under the Process Temperature Sensor Limits
heading. The upper and lower sensor limits may be edited as needed.
The Rosemount 3051SMV accepts Callendar-Van Dusen constants from a calibrated RTD schedule and
generates a special custom curve to match that specific sensor Resistance vs. Temperature performance.
Matching the specific sensor curve with the transmitter configuration enhances the temperature
measurement accuracy.

Under the Sensor Matching heading, the Callendar-Van Dusen constants R
0
, A, B, and C can be viewed.
If the Callendar-Van Dusen constants are known for the user’s specific Pt 100 RTD sensor, the constants
R
0
, A, B, and C may be edited by selecting the Callendar-Van Dusen Setup button and following the
on-screen prompts.
The user may also view the
α
,
β
, and
δ
coefficients by selecting the View Alpha , Beta , Delta button.
The constants R
0
,
α
,
β
, and
δ
may be edited by selecting the Callendar-Van Dusen Setup button and
following the on-screen prompts. To reset the transmitter to the IEC 751 Defaults, select the Reset to
IEC 751 Defaults button.
2.7.7 Module temperature
The sensor module temperature variable is the measured temperature of the sensors and electronics
within the SuperModule assembly. The module temperature can be used to control heat tracing or
diagnose device overheating.
