... 4 Design and function
... Input functionality
If drift monitoring is used for the same types of sensor
(2 × Pt100 or 2 × thermocouple), the mean value calculated from
the two sensors is mapped to the transmitter output signal as a
process variable in redundancy mode.
If a thermocouple is used for Pt100 drift monitoring, the Pt100
sensor (see Electrical connections on page 27) should be
connected to channel 1 and the thermocouple to channel 2.
The measured value from channel 1 (Pt100) is mapped to the
transmitter output as a process variable.
Note
Before configuring the maximum permissible sensor deviation
for drift monitoring, sensor adjustment with respect to the
sensor channel 1 value must be carried out with the help of,
for example. the TTF300 DTM.
Sensor error adjustment in accordance with Callendar-
Van Dusen
Under normal circumstances, the standard Pt100 characteristic
curve is used for resistance thermometer measurement.
However, recent advances in technology now mean that
maximum measuring accuracy can be achieved where necessary
by carrying out individual sensor error adjustment.
Sensor characteristic curves are optimized by using a Pt100
polynomial in accordance with IST-90 / IEC 751, and EN 60150,
and by applying A ,B, C, or Callendar-Van Dusen coefficients.
With the help of the DTM, EDD or FDI package (FIM), these
sensor coefficients (Callendar-Van Dusen) can be adjusted and
stored in the transmitter as a CVDcharacteristic curve. Up to five
different CVDcharacteristic curves can be stored for HART and
PROFIBUS PA, while up to two CVDcharacteristic curves can be
stored for FOUNDATION Fieldbus.
