Capteurs de Pression de Haute Précision, Silicium Micro-Usiné

Typically the readings are not effected by orientation. You may see a shift in the readings on the very low pressure range (0 to 10"H2O and 0 to 1 PSI) if you change orientation but you should be able to calibrate that out in your readout device.

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

We do not recommended using our transducers in a hydrogen application due to embrittlement of the wetted parts when exposed to hydrogen

You would use the +/- 1% FS max

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.

Thank you for contacting Omega engineering, for export related question kindly send an email to exportcompliance@omega.com. Thank you.

This would depend on how small of a signal change the instrumentation you are using to read the signal can detect.

There are no CAD drawings currently available for the PX459 pressure transducers

There is no pressure drop rating for this sensor.

Maxx, the -EH models have a 0.05% BFSL static pressure accuracy, whereas the models without -EH will have a 0.08% BFSL accuracy.

Hello, and thanks for connecting with us. The software icon, for the free software download, is located in under the bullet points (before the Description copy) on the product page https://www.omega.com/pptst/PX409-485_PXM409-485.html Please contact our Tech Support if have any further questions.

Thank you for your inquiry, the information you're requesting will be located on the certificate of calibration.

Thank you for your inquiry, we do not include a calibration procedure, however we do offer calibration services.

Thanks for being an Omega customer. The free software is available here for this product: ftp://ftp.omega.com/public/DASGroup/products/USBH/

Thank you for your inquiry While the construction of a gauge or absolute sensor is fundamentally different, in this case where your sensor has a range of 3,500 psi A is so large it should be fine. This issue is that an absolute sensor has no way to react to changes in atmospheric pressure like a gauge sensor does. The typical worst-case limits in atmospheric pressure changes (if you don't change your elevation) are between 13.5 – 15.0 psi, or about 1.5 psi, this is only (1.5/3500*100) = 0.04% FS change for the sensor, smaller than the error band! You can safely ignore atmospheric pressure changes for this device and offset your device to represent a gauge pressure reading. hope this was helpful?

Thank you for your inquire Overpressure Absolute Pressure: 5 psia: 6 times span 2.5 psia to 1000 psia: 4 times span 1500 to 5000 psia: 10,000 psi maximum Secondary Containment Gage/Diff/Vac/Compound: 10 inH2O to 5 psi: To 1000 psi 15 to 1000 psi: To 3000 psi 1500 to 5000 psi: To 10,000 ps

Thank you for your inquiry, Omega doesn’t support LabVIEW, but customers have told us they use our USBH sensors with LabVIEW : The easy-to-use ASCII data protocol of the USBH sensors can be handled with a standard LabVIEW VI like: Basic Serial Write and Read.vi. (While Omega gladly provides support for our .NET API, we cannot provide support for implementation as a part of LabVIEW). ). If you have any additional questions please contact our customer support department.

There are two versions of the PX409 Pressure Transducers. One version as an analog output of millivolts, Voltage or Current. The other version has a high speed USB output. It appears you have the analog output version with would not have a USB connect on it. You would need to purchase a new PX409 with the part number ending in USBH. This unit has an attached cable with the USB connection on the end

There is no documentation available to guide you in software design for this device.

All the parts of the PX409 series coming in contact with the media (wetted parts) are all 316 Stainless Steel. According to published chemical compatibility charts 316 SS is compatible with Helium

Thank you for your inquiry. Please contact us directly at pressure@omega.com or 1-800-826-6342 to discuss this question.

Thank you for your inquiry, please contact us directly to obtain the HSN number

Thank you for your inquiry, we do offer a quick start manual for the RS485 sensors. This document can be found in the product manual section of our website ( PX409-485 and PXM409-485) if you require additional information please contact one of our Pressure engineers

Hello, Thank you for contacting Omega Engineering. If you want to measure 20 bar absolute you should not use the 17.5 Bar absolute unit, you may damage the diaphragm. Please go with the 30 bar absolute model. Thank you.

These units have been tested to withstand an operating temperature of -49 to 240 Fahrenheit but not for prolonged periods. We do not have data on how the sensor will be affected if you store these transducers under those extreme conditions for longer periods of time.

Thank you for your inquiry, this unit weighs less than 2 pounds

The three available accuracy ranges these sensors are 0.03%,0.05% & 0.08%. Accuracy is based on the full scale range of the sensor. Available pressure ranges from a low range of 0 to 10"wc up to 0 to 7500 PSI

Thanks for your question. The free software is available here for this product: ftp://ftp.omega.com/public/DASGroup/products/USBH/

Avoid exceeding the proof pressure rating of the sensor. You will damage the sensing diaphragm of the unit. It will most not be calibratable once damage

The system requirements are: An up-to-date Windows 7, SP1; .NET Framework 4.5.2 (part of Microsoft’s automatic updates); USB 2.0 port. (USB 3 also works). Please contact our Tech Support if you need any further assistance.
