High Performance Pressure Transducer Long Term Reliability Aerospace Quality

OMEGA’s PX5500 Transducer Series provides high performance in demanding industrial and research applications where accuracy, reliability, and price are important. This transducer has a 10 year MTBF rate and is stable to 0.1% of FSO over an 18 month period. This translates into less down time, fewer test reruns, more time between calibrations, and high confidence in your pressure data. When recalibration is impossible, relying on the high stability of the PX5500 Series transducer may be the only cost-effective way to obtain pressure data over the long term.

OMEGA’s thin film technology makes this premium performance possible. The strain gages and associated structures are sputter-deposited directly onto the pressure sensing element thus eliminating the need for adhesives. The resulting molecular bond between the sensing element and the strain gages ensures virtually no shifting, drifting, or 'creep' in the performance of the transducer.

The micro-geometry design of the PX5500 sensing element results in a very small, low mass sensor that reduces effects of mechanical vibration and shock. The PX5500 gives you the accuracy, reliability, and stability at competitive prices.


The PX5500 is also available in metric configurations, with G1/4 or G1/8 ports, and models from 0-1 to 0-600 bar pressure ranges. Please see the PXM5500 for complete details, or contact our Pressure department for more information..
