ADDENDUM - 1011C DATA OUT VOLTAGES AND CONVERSIONS
Data Out Conntector Pins:
A
-DPI Dew point indication – binary output of 0 V or 5 V.
If 1011C is balanced and controlling, output is 5 V, else output is 0 V. Note: this is listed
as RTD in the manual.
C-
Balance Vbal (0-10 V range)
Output of signal from optics. 1011C is balanced and controlling on dew or frost when Vbal
is close to 5V.
E
-PRESSURE for Pressure sensor option. Vpress (0-10V range)
Press(mb) = 100* (Vpress – 1.6)/.64
G
-TEMPERATURE (Dew Point) Vdf (0-10V range), Tdf range (-75 to +50)
Tdf = 12.5 * Vdf - 75
B,D,F,H
are all corresponding ground connections for the outputs listed above.
