Process Param. -
Operating
Temp.
AUTO - OOS Use this function to specify a fixed value for the process temperature
(operating temperature).
! Note!
The sensor (measuring pipe and bluff body) expands differently
depending on the existing process temperature. This has a proportional
effect on the accuracy of the measuring system since the device was
calibrated at a fixed calibration temperature of 20 °C (293 K). However,
this effect on the current measured value and the internal totalizer can be
compensated by entering an average process temperature in this function.
User input:
5-digit floating-point number
Factory setting:
20°C / 293.15 K / 68 °F / 527.67 R
! Note!
The unit is displayed in the "Process Param. – Operating Temp. Unit"
parameter (Page 95).
" Caution!
This setting does not change the permitted temperature range of the
measuring system. Please pay particular attention to the temperature
application limits specified in the product specification (Page 67).
