Screen shot of charting windowCharting Window – The addition of a charting window allows you to see your data graphed in real time. The Y axis is configurable to allow simultaneous graphing of multiple engineering units. You can output the image of your data to a png file.

Channels Window - Display data from all of your sensors simultaneously. Each channel has configurable user alarms, three data filters, tare, resettable low/high indication, and sample rates ranging from 30 minutes to 1000Hz.

Logging Window – A new xls filetype output option presents preformatted data for readability. In addition, Live Statistics are displayed, including the sensor information, the start/stop time, the number of samples taken, the current reading, and the High/Low readings. With the logging window, you can capture your data for later analysis.

Rated 5 out of 5 by from One down 999 to go. I rarely write reviews. I bought the PX409-2.5VUSBH a few weeks back for the apparent ease of use of the USB interface. Admittedly, I have had some issues with the sensor from a software standpoint (mostly nagging "why can't it do that" issues) and a mechanical standpoint (can't figure out how I sprung the sensor), but the bottom line is Omega's Ohio team stood by me every step of the way. They helped me fix software issues and when the gage sprung they helped analyze the problem and even offered to replace the unit. The truth is that the website got me to buy the first one but the service will get me to buy the next 1000! Well done team!

Rated 5 out of 5 by from Excellent and easy to use! This is the Third Omega USBH pressure transducer that I have purchased for our lab. We now have a 50, 250, and 500 psi units. Basically no training required due to the ease of use with the Omega software.

Rated 5 out of 5 by from Easy to use, high precision plug & play! Spent a little time trying to find a pressure transducer that can easily connect inline to NPT and/or luer fitting to measure and log pressure in real-time and this was by far the most cost-effective option with free software to boot!

Rated 5 out of 5 by from Worked right away with almost no set up time Software was easy to install, it had no problem finding the sensors. Features were easy to use, I was taking data within a few minutes. Way easier than I expected.

Rated 5 out of 5 by from Plug and play pressure transducer We needed a way to log pressure response in real time, and were reticent to piece together a system. The PX409 series made it very easy to connect to our fluid path and take readings on a laptop. It is accurate, reliable, and typical Omega high quality.

Rated 5 out of 5 by from Easy Works good - accurate. Has a problem exporting directly to excel but can be worked around by exporting to file.

Rated 5 out of 5 by from Great tool . Can you add a slight modification? Dear Omega Engineering team, We would like to thank you so much for the excellent transducer we have bought from you almost a couple of months ago. The Transducer's accuracy and ability to measure up to 1000 readings per second helps us to achieve what exactly we are looking for. Thank you, Armia

Rated 5 out of 5 by from Works great! Excellent capture rate, very robust design, but most importantly it's totally plug-and-play. Super easy to setup and start capturing data.

How do you calculate BSL when the only variable/dataset you can measure is Pressure?

Asked by: JimW
Thank you for your question? The PX409-USBH are digital output models that communicate directly to your PC via the digital transducer application. Since you are not taking a analog signal and scaling the output, in this case you can consider accuracy to be a percentage of your FS (Full Span) So the pressures you apply should be within +/- 0.08% of the rated FS of the transducer.

Does the operating temperature range correspond to ambient temperature or the temperature of the medium being sensed?

Asked by: JerryG
Thank you for contacting Omega. Operating temperature range is really the combination of the ambient and media temperature, the electronics inside of the device must remain below the specified temperature. To determine the internal temperature of the device you would need to account for the effects of conductive, convective, and radiant heat transfers, this can be challenging, it is best to play it safe, if you are measuring media with significantly higher or lower temperature than the specified operating temperature I would recommend a cooling element. Please contact our Tech Support if you need any further assistance. https://www.omega.com/pptst/PG-CT.html
