OMEGA’S high accuracy PX409 Series Pressure Transducers have a proven record in high-performance commercial and aerospace applications for over 25 years. A full Wheatstone bridge is diffused into a silicon wafer and then micro-machined to exacting standards to produce a silicon sensor that has excellent stability, linearity, repeatability, and excellent long-term stability. At our state-of-the-art facilities, transducers are calibrated using extremely high accuracy equipment, and a 5-point NIST traceable calibration certificate is included with each model. All Stainless Steel wetted parts, welded construction and premium temperature compensation makes transducers suitable for use in tough industrial environments. OMEGA’s free downloadable Software provides advanced data logging capabilities hence add value and flexibility to your transducer performance.
Build/Order/Ship OMEGA’S MM Series Custom Pressure Transducers to meet your pressure sensing requirements: As a lead pressure transducer manufacturer, Omega has developed a new interactive configuration tool that provides a fast and simple way to build custom transducer suitable for application. MM Series custom transducers allow for over 1-million possible combinations of parameters such as pressure type, range, unit, material, output, accuracy, fitting, temperature compensation range, and electrical termination. At the end of the process, the Configurator will provide a part number, price and delivery time for the transducer. For more information about Configurator, Options Selection and FAQs.

Some of the most Popular Applications of Pressure Transducers include:
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.
| Output Model | Power Supply |
| 0 to 5 Vdc | 10 to 30 Vdc@10 mA |
| 0 to 10 Vdc | 15 to 30 Vdc@10 mA |
| 4 to 20 mA | 9 to 30 Vdc |
| 10 mV/V | Ratiometric 5 to 10 Volts DC |
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.

I have brought 8 of PX459-500GI and I'm looking for a wiring diagram for them, they have and M12 cable
Thank you for your inquire.
The wiring is shown on the calibration sheet that is included. We can also generate a new copy if the do not have it.
Please contact us at pressure@omegfa.com. For a copy if needed.
Please include the serial number.

Hi. Is it possible to re-range existing sensors? We have a few 409 series pressure transducers that we would like to calibrate for another pressure range than that originally purchased for.
Thank you for your inquiry, due to the construction of the PX409 series it is not possible to calibrate to a different range and maintain the accuracy.

The wiring for Model PX409-015G5V Shows the red wire is + EXC. What is +EXC and how is it applied? It different than +24vdc supply?
Thank you for your inquire
Please contact us directly to review in detail your wiring question.

How do I install this sensor in a pipe?
This sensor has a 1/4 npt male pipe thread as it's process connection. You will need to install a 1/4 npt female fitting on your pipe. On small diameter pipes you can usually install at tee fitting in-line with the pipe that would have this connection.

I have Item# PX409-015VUSBH, 0 to -15, vacuum. Occasionally, there will be small amounts of positive pressure applied to the gauge, no more than 2 psi. Will this potentially damage the gauge? How much positive pressure can I apply until it does damage.
Hello, Thank you for contacting Omega Engineering, occasional small positive pressures in the magnitude or one or two psi should not damage the diaphragm significantly. It is however not recommended since it may affect your zero balance over time.
Date published: 2023-05-04
Does the pressure transducer have a specific install orientation? Any problems with a horizontal verses vertical install?
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.

On the Omega software for USB PT: If anything happens that makes the program freeze up (unplugging the PT) or laptop die (power out) the past data seems lost forever. I've looked for a log file but cannot find anything. How can I recover the data?
You can recover the data as long as you haven't started logging again. I am sending a pdf which contains a troubleshooting guide that should help you locate the logged data. Emailing it to dda@alumni.caltech.edu

Can the PX409 series be used to measure oil pressure? I cannot find any info stating the acceptable mediums.
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.
