6.9.4 Conversion visibility/dust concentration with menu item “Conversion μg”
Configuration k/μg defines whether the visibility or the dust concentration are to be output
in μg on the display and the analog output. Both values are always output via the PROFIBUS
and the Modbus.
The coefficients for conversion of the K-value in a dust concentration are stored under
menu item Coefficients.
The conversion is performed according to the following formula:
μg = a0 + a1 * k +a2 * k²
The values have the following default settings:
a0: -3.62 a1: 70.24 a2: 0.13
Fig. 83: Conversion k/μg value
Fig. 84: Selecting coefficients for conversion k/μg value
▸ Select the coefficient with “Enter”.
▸ Enter the required value.
▸ Use “Save” to save the value.
NOTE: When the dust concentration is activated, k becomes μg
For representation of visibility in μg, the value in the VISIC100SF display is not output as
K-value but as μg.
The transmitted measuring range in μg is 0 to 1500μg.
