Transmitter-Sensor Matching — Each sensor has a
unique Resistance-Temperature (R-T) curve. This
curve is determined by a 4th order Callendar Van Dusen
Equation. By determining the unique Calendar Van
Dusens constants for a specific sensor, the exact R-T curve can be determined.
The Model 644 uses
these CVD constants to create a unique R-T curve for the
specific sensor; the transmitter then uses this curve
for the highest accuracy
available. This is known as transmitter-sensor
matching, which can increase your temperature point
accuracy by up to 75%.
What
are the Sources of Temperature Measurement Error?
Temperature
measurement error is comprised of both transmitter and
sensor related components. Transmitters exhibit
inherent electronic errors as well as errors related
to changing ambient temperature. The
majority of error in a temperature measurement system
is comprised of sensor error!
