OPERATION
The transmitter is factory calibrated with standardized sensors, not
requiring any adjustment by the user.
Small corrections can be accomplished through the
TxConfig II
software (in units of temperature).
The user may choose the sensor and the range that best fits its
application. The range chosen must not exceed the maximum
measuring range defined for the sensor and must not be less than
the minimum range for the sensor.
It is important to note that the accuracy of the transmitter refers to the
maximum range of the sensor used, regardless of the actual range.
Example:
•
The sensor Pt100 has a max. range of -200 to 650 °C and total
accuracy de 0.08 %.
•
Thus, we can have an absolute error up to 0.68 °C (0.08% of
850 °C).
•
This error is possible in a wide range as the maximum (-200 to
650 ° C) or in a narrower range, set by the user as (example) 0
to 100 ° C.
