Heavy Duty Pressure Transducers

PX2 Series, 1 bar to 70 bar | 100 kPa to 7 MPa | 15 psi to 1000 psi

Table 4. Pressure Reference Types

Pressure Reference

Description

Absolute

Output is proportional to the difference between applied pressure and a built-in fixed reference to

vacuum (zero pressure), where the minimum operating pressure is set to absolute zero pressure

(perfect vacuum).

Sealed gage1

Output is proportional to the difference between applied pressure and a built-in fixed reference to

1 atmA, where the minimum operating pressure is set to 14.7 psiA (1 atmA).

Vented gage2

Sensor measures pressure relative to ambient pressure. Output is proportional to the difference

between applied pressure and atmospheric (ambient) pressure, where the minimum operating

pressure is set to atmospheric pressure.

1

Sealed gage option only available in pressure ranges at or above 100 psi.

2

Vented gage option only available in pressure ranges between 100 psi and 667 psi.
