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.

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 2 out of 5 by from Word of Caution The product performance was great, but there is a major design flaw. The cable connection option has the cable connected to the body by a nut that if loosened and taken off will break the unit. Whereas the PX409 series differential transducer instead does not have this problem, it has a sealed connection that doesn't allow you to break the unit so easily. The reason I was attempting to take the nut off in the first place was because it was loose and the unit was dunked under water for cleaning so I was trying to make sure the unit would dry out fully before supplying power to the transducer.

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?

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?

What is the inside diameter and depth of the sensing port within the Male 1/4 NPT port on model PX309-100A10V ?

Asked by: Brendon
Thanks for your inquiry. Would only have available a approximation. 1/8 of an inch The depth would fluctuate Hope this was helpful.

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.

What is the input impedance and output impedance of the PX309?

Asked by: JWeng
We do not provide the input/output impedance for the PX309 0 to 5VDC output units. The impedance can widely vary due to the internal components used in the each sensor.

What is the difference between a compound gauge and absolute gauge?

Asked by: jackie270
The compound gauge are measuring a vacuum or positive pressure relative to the atmospheric pressure. The unit has a vent to atmosphere for the reference. The absolute gauge units measure pressure relative to an internal sealed vacuum reference.
