F igure 29 shows a Function Block Diagram using a DEWP function block. This application uses the Dew
H
Point function block to calculate dew point based on using a carbon probe. A typical example might be for
control of an endothermic atmosphere generator. Alternatively, a Honeywell dew point transmitter could
be used for a more direct measurement.
Revision 11
2/07
0 Allows you to adjust % Carbon
measurement to compensate
for variations in the amount of
CO in the carrier gas.
1 Function block will use the
actual % Carbon Monoxide
that is defined through an
analog input.
