FUNCTIONAL SPECIFICATIONS

Automatic Temperature Compensation:

3-wire Pt 100 or Pt 1000 RTD
Conductivity: 0 to 200°C (32 to 392°F)
Resistivity: 0 to 100°C (32 to 212°F)
Low Conductivity: 0 to 100°C (32 to 212°F)

Diagnostics: The internal diagnostics can detect:

Calibration Error ROM Failure
Temperature Slope Error Zero Error
High Temperature Warning CPU Failure
Low Temperature Warning Input Warning

Once one of the above is diagnosed, the Xmt-C will
display a message describing the problem.

Digital Communications:

HART: PV, SV, and TV assignable to measurement

(conductivity, resistivity, or concentration), temper­ature, and raw conductivity. Raw conductivity is
measured conductivity before temperature correc­tion.

Fieldbus: Three AI blocks assignable to measure-

ment (conductivity, resistivity, or concentration),
temperature, and raw conductivity. Raw conduc­tivity is measured conductivity before temperature
correction. Execution time 75 msec. One PID
block; execution time 150 msec. Device type:

4084. Device revision: 1. Certified to ITK 4.5.
