Les capteurs de haute précision piézorésistifs Omega ont fait leurs preuves durant plus de 25 années dans des applications de haute performance commerciale et aéronautique. La technologie piézorésistif utilise des jauges de contrainte implantées dans une membrane stable en silicium. La membrane est coupée en dés, chacun contient un pont de jauge de contrainte. Il est protégé du milieu extérieur par un boîtier étanche en acier inoxydable fermé par un joint métal à verre et une membrane en acier inox.
La pression appliquée sur la membrane est transférée à l’élément sensible par un petit volume d’huile silicone. Cette construction assure un transducteur robuste doté d’une précision excellente, une bonne stabilité et les effets thermiques faibles. Sa robustesse est assurée par notre conception unique d'une enceinte de confinement secondaire de fluide en cas de rupture de membrane.
Chaque capteur est sévèrement testé en pression et température. Les capteurs sont étalonnés avec des appareils de haute précision, et livrés avec un certificat d’étalonnage raccordé à 5 points. La fiabilité de l'élément de capteur sur base piézorésistive donne une excellente stabilité en long terme, une bonne répétabilité et les effets thermiques très faible et pour le prix d’un capteur de pression moins performante. En standard les caractéristiques de l'PX409 comprennent la protection de l'électronique et de l'élément sensible contre l'inversion de polarité, EMC et les fluctuations de tension d'alimentation. Les classements de Sécurité Intrinsèque et CSA sont disponibles en option.
Les gammes de produits les plus courants sont stockés pour une livraison immédiate. D'autres configurations sont disponibles dans des délais courts.

Great transducersSimple, easy to use, accurate, quick lead times, and a fraction of the price of competitors!
You can specify the "pressure type" measurement as "gauge" or "vacuum". What exactly does the vacuum pressure type mean? It is the same as absolute pressure?
Asked by: JoeyH9
A vacuum-type sensor is like a negative gauge, the signal has a negative scale, meaning the low output will be when the pressure is at zero, and as the pressure DECREASES the signal will INCREASE

Can the PX409 series be used to measure oil pressure? I cannot find any info stating the acceptable mediums.
Asked by: Aaron20
Thanks for your Question. The PX409-001CG10V is a 316 Stainless Steel unit that can be used to measure oil. Please check your oil chemical compatibility with 316SS. Please call or email us at pressure@omega.com with any further questions.

Will MMDDB2.5BIV10P4C5T1A3, listed as bi-directional differential pressure, 0-2.5 psi, read vacuum if the low port is connected to the vacuum process and the high port open to atmosphere? Will it work with both ports across different vacuums?
Asked by: Ed5280
If you connect a vacuum to the low and leave the high port open to atmosphere the unit will output 0 to -10VDC if a vacuum id applied to the LOW port. If you apply varying vacuums to both ports the unit will respond with a sign representing the difference between the vacuums applied ranging from -10VDC to +10VDC

What is the resolution limit on this device? I'm interested in your 0-2 bar sensor and what the lowest pressure value it is able to measure accurately.
Asked by: Ben_
Resolution would depend on how small of a signal change the instrumentation used to read the 0 to 10VDC output can resolve. The sensor will read from 0 to 2 bar but the lower 10% of the range (0 to 0.2 bar) would end to be less accurate

Are the high accuracy transducers rated for use with hydrogen?
Asked by: jrea98
We do not recommended using our transducers in a hydrogen application due to embrittlement of the wetted parts when exposed to hydrogen

Hi,
we have a PX409-16BI transmitter that we are developing a validation procedure for. Stated zero and span tolerances are +/- 0.5% FS typical with a +/- 1% FS maximum. Which should I use for validation? (BSL is not a validation tolerance)
Asked by: John314
You would use the +/- 1% FS max

When you say accuracy, are you referring to the resolution or the measurement, or the actual measurement accuracy? What are the respective values of each?
Asked by: Julian
Thank you for contacting Omega. The PX409 is a full analog path sensor, meaning it's resolution is essentially infinite. The accuracy we specify details the uncertainty of the output. We specify the combined uncertainty contributed by non-linearity, repeatability, and histories.
