SERIES CPG 2500

8.3 Analog Output

The CPG 2500 can be configured at the time of manufacture to have voltage output that
is directly proportional to the full scale pressure range of the A and/or B channel pres-
sure transducer(s) in the instrument. This output is available from a 4-position remov-
able connection on the rear panel.

Channel A Signal +

The analog signal is set at the factory to one of the following ranges:

-1 to +1 vdc

0 to +1 vdc

0 to +5 vdc

0 to +10 vdc

The formula to derive the measured pressure from the output voltage is:

voltage span

x measured pressure + voltage minimum
pressure span

The following example shows output voltages for two pressure values using a 0 to 250
psia full scale transducer with a 10 VDC analog signal:
