What is the accuracy of the PX409 Series?

The PX409 Series has a high accuracy of ±0.08% BSL and includes linearity, hysteresis, and repeatability. To obtain their high accuracy and stability, the PX409 Series uses state-of-the-art digital mapping of the temperature, pressure, and output performance of the silicon sensor in conjunction with a custom ASIC to provide dynamic thermal compensation across the temperature and pressure parameters.

Is the PX409 Series suitable for any liquid and gas applications?

OMEGA piezoresistive pressure transducers have a proven record in high performance commercial and aerospace applications for over 25 years. The piezoresistive process and the construction of the PX409 Series provides a very rugged transducer with exceptional accuracy, stability, and thermal effects. The PX409 Series is all stainless steel (316 SS) wetted parts. Please ensure the media under measurement is compatible with wetted parts.

What is the power supply for the PX409 Series?

The power supply of the PX409 Series depends on the output of the chosen model and power supply fluctuation protection is standard on all models. Please refer to the table below for details.

Is the PX409 Series calibrated?

The Px409 Series are calibrated using extremely high accuracy equipment and a 5-point NIST traceable calibration certificate that is included with each transducer. It is recommended that the sensor be recalibrated once a year. The most popular ranges and configurations are stocked for immediate delivery. All others typically have a very short lead-time.

How can I install a PX409 Series in a pipe? Does it need a specific orientation (vertical or horizontal)?

The PX409 Series has a ¼ - 18 NPT male fitting that is threaded into a pipe fitting for installation. There is no specific orientation needed – the unit is calibrated in the vertical direction with fitting down. The sensor is designed to be quickly customized to meet your exacting specifications, often with fast delivery.

Rated 5 out of 5 by from Great product Great product. Works well. Software is simple and easy.

Rated 5 out of 5 by from Precise, repeatable, and easy to use These sensors replaced some older models that weren't rated for the pressure in my application. The new ones seem very reliable and the sensor-to-sensor variation between the two that I bought is much smaller than it was for the old ones.

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
Vacuum pressure type means it's a sensor scaled to measure vacuum reference to Gage (reference is vented to the atmosphere). This is different than an Absolute unit which is reference to a sealed internal vacuum reference.

What is the recommended calibration frequency for these pressure transducers?

Asked by: btorrec
The NIST traceable calibration report shipped with the sensor is valid for 1 year after the sensor ships from Omega. We recommend recalibration once a year calibration cycle.

Does the pressure transducer have a specific install orientation? Any problems with a horizontal verses vertical install?

Asked by: mike_mcc
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.

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.

I have to return a couple of these pressure sensors to a client overseas (UK). But before my company can ship them, we need to know the ECCN export number. Please supply the ECCN for these items... PXM419-070BA10V. Thank you.

Asked by: ziggy19
Thank you for contacting Omega engineering, for export related question kindly send an email to exportcompliance@omega.com. Thank you.
