Description

Absolute

0psiA

+Prange

Output is proportional to the difference between 0psiA (Pmin) and pressure

applied to Port 1.

Differential/

Bidirectional

-Prange

+Prange

Output is proportional to the difference between Port 1 and Port 2. Output

swings positive when Port 1> Port 2. Output is 50% of total counts when

Port 1=Port 2.

Gauge

0psiG

+Prange

Output is proportional to the difference between 0psiG (Pmin) and Port 1.

Output swings positive when Port 1> Port 2.

Vacuum

-15psiG

+0psiG

Output is inversely proportional to the difference between -15psiG pressure

(Pmin) and pressure applied to Port 1.

Compound

-15psiG

+Prange

Output is proportional to the difference between -15psiG pressure (Pmin) and

pressure applied to Port 1.

*Prange is equal to the maximum full scale pressure specified in the ordering information.
