OMEGA’s PX309 Series Stainless Steel Pressure transducers below 100 psi use a high accuracy silicon sensor protected by an oil-filled stainless steel diaphragm. Units 100 psi and above use silicon strain gages molecularly bonded to the stainless steel diaphragm.

We provide a complete range of services—from product inception, through design and prototypes, to manufacturing and testing. Our application engineers work closely with our customers to customize, design or create entirely new products. Call us—whether you’re an OEM, manufacturer, or end user.

The PX309 is also available in Metric configurations; please see the PXM309 for complete details, or contact our Pressure department for more information.

Rated 4 out of 5 by from compact and reliable Have purchased several of these transducers over the last 10 years and do not recall ever having to replace one due to failure. I usually get the 319 series and my only complaint is that there is no key on the connector to simplify pin alignment. They are also offered a wide range of pressure ratings.

Rated 5 out of 5 by from Quality instruments The instruments from omega are always very reliable and accurate as well. I frequently purchase multiple products from them both for business and personal use and will continue to do so. Their customer service is great as well and they are easy to place an order or to fill a quote request. Very happy with them as a vendor.

Are there any limitations for using the PX309 series transmitters under constant exposure to hydrogen gas (pressures up to 3k psi)? (hydrogen embrittlement specifically) Thank you.

Asked by: alphaTech
The PX309 should not be used to measure hydrogen. Embrittlement will occur.

Where can I find the transfer function for a PX309-100A10V? Is it included in the calibration documentation or do I have to generate it myself?

Asked by: dtorgersen
I am reading voltages off the sensor and using custom software to output a pressure. where do i find the equation that converts the sensor output voltage to pressure?

Is there a manual for installing and programming the PX309-5KG5V? I tried accessing the ftp.omega.com site, but it wasn't working. There also isn't a user manual on the product site. I am trying to connect it to a Arduino Uno and a 12V battery.

Asked by: nbosio1001
The PX309-5KG5V is simply an analog output sensor generating a 0 to 5VDC signal over it's 0 to 5000 PSI pressure range. There is no programming necessary and there is no manual. A wiring is available on both the specification sheet on our website and the calibration report that is shipped with the unit. This is a 3 wire device and wiring is as follows. Red wire should connect to the positive(+) side of our 12V battery. Black wire should connected to both the negative (-) side of your 12V battery and the negative (-) or low input of your readout device. White wire should connect to the positive (+) or high input of your readout device. We would have not have any info on how specifically you would connect this to a Arduino Uno

What is the maximum load that can be used in series with the PX309-1KA (4-20mA output)?

Asked by: ExampleName
By &quot;load&quot;, I meant electrical load (i.e. resistance value, measured in Ohms). Sorry if that wasn't clear form the question. From another answer stating the max current is 24mA, the max resistance would be 1000 Ohms. Is this correct?

Does Omega PX309 read above the +15 PSI maximum pressure with less accuracy or the15 PSI is the maximum positive pressure that can read? and what will happen if my sample produces more pressure than the specified limit, is that going to damage the sensor?

Asked by: ZARA
Thank you for your inquiry, the PX309 15PSI has a Pressure Overload rating of 3 times rated pressure. The accuracy of the unit is based on zero to full scale, we do not guarantee specifications over the rated pressure.

Will PX309-100G5V work with Both Liquid and gas environments?

Asked by: Prem N
Hello, Thank you for contacting Omega Engineering. The PX309 is compatible with both gases and liquids. You will however have to make sure your media is compatible with the wetted parts.

There are 4 output options&quot;4-20mA, 0to5V,0to10V, and 'mV output'. What I want is a real time dynamic output of the instantaneous pressure level. I know this much:4-20mA does NOT do what I want. Do any of the others match my description?

Asked by: B3arKat
The response time of the mV/V and DC Voltage output PX309 transducers is approximately 1 millisecond. While the response is fairly quick these units are designed for static pressure measurement. There are dynamic pressure sensors that are of piezo-electric design the have a response in the microsecond range. Omega does not offer this type of sensor

Can the PX309 be installed onto a hydraulic system? Can it be used with hydraulic oils to take readings without damage? Thank you

Asked by: Edwards
The PX309 is constructed with stainless steel wetted materials, which would be compatible with hydraulic oils.
