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.

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.

Great Product!
Exceptional Product. 5/5! Always order these from Omega and they are very consistent with their deliveries, while providing an easy-to-maneuver website to order them.

Nice!
Great product! Cheap but work accurately. Hopefully there will be more in stock so we do not need to wait for production.

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.
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?
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?

Can the PX309 be installed onto a hydraulic system? Can it be used with hydraulic oils to take readings without damage? Thank you
The PX309 is constructed with stainless steel wetted materials, which would be compatible with hydraulic oils.

What is the supply current on the PX309 whose output is 100mV?
We cannot provide a fixed value for the current draw of the 100mV output version of the PX309 Series. The impedance can widely vary due to the internal components used in the each sensor. The current draw however would be extremely low.
Date published: 2021-05-04
Are FPW-15 or PSR-24 recommended as excitation sources for PX3093KG5V transmitter?
Yes, The PX309 will run on any DC voltage between 9 and 30 VDC so either supply will work.
Date published: 2020-10-02
I would like to use in an application where the fluid could come into contact with food. Does this transducer have any FDA certifications (FDA 21 CFR or similar).
The PX309 are designed for general use. They do not have any FDA certifications.

What is the inside diameter and depth of the sensing port within the Male 1/4 NPT port on model PX309-100A10V ?
Thanks for your inquiry.
Would only have available a approximation.
1/8 of an inch The depth would fluctuate
Hope this was helpful.

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