Description

Absolute

Output is proportional to difference between applied pressure and built-in reference to vacuum (zero

pressure).

Gage

Output is proportional to difference between applied pressure and atmospheric (ambient) pressure.

Differential

Output is proportional to difference between pressure applied to each of the pressure ports (Port 1 – Port 2).

Completed Catalog Listing Example

Figure 3 shows catalog listing ASDXAVX001PGAA3. It is an AV package, 1 psi gage sensor, with 3.3 Vdc operation using a 10%

to 90% calibration.
