The micro-machined to precision piezoresistive process uses strain gages molecularly tolerances and then has embedded into a highly stable silicon wafer. The silicon strain gages molecularly embedded into it. wafer is diced into individual die which each contain a Strain gage shown magnified full strain gage bridge. The die is mounted in a sealed 500% 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. Strain gages shown larger than actual size. A unique design ruggedizes the transducers by providing secondary fluid containment in the event of a diaphragm rupture. temperature and pressure parameters. The inherent stability of the piezoresistive core provides excellent At our state-of-the-art facilities, automated test long term stability, repeatability and very low thermal equipment performs pressure and temperature cycling effects at the price of much lower performance on 100% of the PX409 transducers. The transducers transducers. Standard features of the PX409 Series are then calibrated using extremely high accuracy also include protective features built into the electronics equipment and a 5-point NIST traceable calibration and the pressure element.
