Sensor Linearization
Key to the accuracy of several of these 4-20mA transmitters is their ability to
linearize the output of many sensors. The platinum RTD, for example, has a
very predictable resistance vs temperature characteristic. Its uncompensated
response, however, has a substantial non linearity (several percent,
depending on the range) that peaks at the midpoint. Components noted
above include circuitry to dramatically improve the sensor nonlinearity and
reduce the total error 40 to 1 (see corrected response). The XTR103,
XTR105, XTR112 and XTR114 are optimized for signal conditioning and
linearization of RTD temperature sensors and some bridges.
Ratiometric sensors of many types (those whose output is proportional to an
excitation voltage or current) can be linearized with these techniques.
Voltage-excited bridge sensors (strain gages, for example) often have an
upward or downward bowing response (see right). The XTR104 and XTR106
can substantially improve the accuracy of these devices. They achieve up to
a 20:1 improvement in transfer function linearity.
