The PX624 has been discontinued, please see the PX409
series as a possible substitute or consult OMEGA's Pressure
Engineering department.
OMEGA's PX624 Series
transducers combine the time
proven precision and stability of the
photo-optical sensor with state-ofthe-
art SMD electronic circuits.
These features provide exceptional
performance with accuracies of
±0.05% of span or better.
For barometric and absolute ranges
up to 30 psia, exceptional long-term
stability is ensured by the inclusion
of a getter material in the evacuated
reference chamber. This material
acts as a sponge to absorb stray
gas molecules as they are released
from the surface of the reference
chamber. This ensures the integrity
of the vacuum reference over time.
Each unit is furnished with a 20
point certificate of calibration
traceable to the National Institute of
Standards and Technology (NIST).
The wetted material are 300 series
stainless steel and Inconel X718.
This combination ensures long life
and broad media compatibility.
Standard pressure fittings include
¼ male NPT and Aminco/ Autoclave
F250. For convenience, the zero
and span adjustments are
accessible with out removing the
cover.
