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

certificate that is included with each transducer. To

obtain their high accuracy and stability, the PX409

Series use state-of-the-art digital mapping of the

temperature, pressure and output performance of the

silicon sensor in conjunction with a custom ASIC to

provide dynamic thermal compensation across the

temperature and pressure parameters. 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

a very short lead-time.
