Omega piezoresistive pressure transducers have a
proven record in high performance commercial and
aerospace applications for over 25 years. The
piezoresistive process uses strain gages molecularly
embedded into a highly stable silicon wafer. The silicon
wafer is diced into individual die which each contain a
full strain gage bridge. The die is mounted in a sealed
chamber protected from the environment by glass to
metal seals and a stainless steel diaphragm.
A small volume of silicone oil transfers the pressure
from the diaphragm to the strain bridge. The
construction provides a very rugged transducer with
exceptional accuracy, stability and thermal effects. A
unique design ruggedizes the transducers by providing
secondary fluid containment in the event of a
diaphragm rupture.
At our state-of-the-art facilities, automated test
equipment performs pressure and temperature cycling
on 100% of the PX409 transducers. The transducers
are then calibrated using extremely high accuracy
equipment and a 5-point NIST traceable calibration

PX409 SERIES SILICON WAFER TECHNOLOGY
PX409 Series uses a highly stable silicon wafer which is
micro-machined to precision
tolerances and then has
strain gages molecularly
embedded into it.
Strain gages shown
larger than actual size.
certificate is included with each transducer. The
inherent stability of the piezoresistive core provides
excellent long term stability, repeatability and very low
thermal effects at the price of much lower performance
transducers. Standard features of the PX409 Series
also include protective features built into the electronics
and the pressure element. Reverse polarity, EMC, and
power supply fluctuation protection are standard on all
models. Intrinsically Safe and CSA ratings are optional.
The most popular ranges and configurations are
stocked for immediate delivery. All others typically have
very short lead-time.
