Supported Applications
The Omega PX4600 series is a family of solid-state, dielectrically isolated pressure transducers housed in a TO-8 transistor case for OEM and printed circuit board mounting. The sensing element is a micro-machined diffused silicon diaphragm with a 4 active arm bridge, giving accurate, highly reliable pressure measurement in a very small, light package.
Because of their small size and light weight, these transducers are well suited to demanding vibration and shock environments, including fixed wing aircraft service, and they are compatible with most industrial fluids and oils. Both gage and absolute pressure versions are offered, so the series can be built into instruments, test equipment, and embedded OEM designs.
Operating Conditions & Performance
The PX4600 series covers standard ranges of 0 to 15, 20, 50, 100, 200, and 300 psi in both gage and absolute pressure, with corresponding metric ranges from 0 to 1.0 bar up to 0 to 20.7 bar. Combined accuracy is ±0.25% FSO, covering linearity, hysteresis, and repeatability.
Each transducer is excited at 10 Vdc and provides a nominal output of 30 mV ±10% @ 10 Vdc, with a zero balance of 0 mV ± 5% FSO. Input resistance is 2000 Ω minimum and output resistance is 1000 to 1500 Ω.
- Operating temperature: -55 to 150 °C (-65 to 300 °F).
- Compensated temperature: -55 to 121 °C (-65 to 250 °F).
- Proof pressure: 250% of rated pressure, up to 500 psi max.
- Burst pressure: 300% of rated pressure, up to 500 psi max.
- Shock: 100 g, 11 ms half sine wave without damage.
- Weight: 5 g (0.2 oz) maximum.
Under 35 g peak sinusoidal vibration from 10 Hz to 2000 Hz, output does not exceed 0.04% FSO/g for the 15 psi range, decreasing to 0.005% FSO/g for the 100 psi range and above. Wetted parts are Nitride, Pyrex glass, epoxy, and Kovar, and the units are built to NIST Standard and are CE marked.
Configuration Options
All PX4600 models share the same solid-state silicon sensing element, TO-8 transistor case, 12-pin connector, 10 Vdc excitation, and 30 mV ±10% output. What changes from model to model is the pressure range and whether the transducer reads gage or absolute pressure.
Pressure Range
Standard ranges span 0 to 15 psi through 0 to 300 psi, with the smaller ranges suited to low-pressure sensing and the higher ranges to broader spans. The same span is expressed in metric form from 0 to 1.0 bar through 0 to 20.7 bar.
Pressure Type
Both gage and absolute versions are available for the offered ranges, letting the same mechanical package serve applications referenced either to ambient or to a sealed vacuum reference.
Physical Package
Each unit measures 15.2 mm (0.60 in) in diameter with a 19.1 mm (0.75 in) stem length and a 12.7 mm (0.50 in) body height, and terminates in a 12-pin connector.
Key Product Differences
The catalog number is built from the PX4600 base followed by the pressure range and the pressure type. For example, PX4600-015AV and PX4600-015GV share the 0 to 15 psi range while differing in pressure type.
Representative models across the lineup include:
- PX4600-015GV and PX4600-015AV — 0 to 15 psi.
- PX4600-100AV and PX4600-100GV — 0 to 100 psi.
- PX4600-300GV and PX4600-300AV — 0 to 300 psi.
Show Ratings & Reviews
We purchase several of the PX4600 series transducers from Omegadyne which we solder to our printed circuit boards. Can you provide the specifications for the recommended mounting distance from the PCBA surface and any other specifications for soldering.
Omega Engineering recommends a minimum of .125 gap between the PX4600 sensor housing and printed circuit board to minimize stress to the glass hermitic seals during temperature swings.

What is the PX4600 maximum input resistance?
Thanks for the inquire
please see below
(input resistance is between 900 and 1500 ohms )
Date published: 2021-05-12
how should this part be tested to ensure hermetic seal is good? how does one know if seal is bad?
Thank you for your question?
We will need some more information before this can be answered completely
This will be addressed by the engineering depart in detail by email.

Is it pressurize directly to the backside of the pressure die (no metal diaphragm)? Is it compatible with natural gas air pressure media?
Pressure is measured by the small silicon glass diaphragm mounted in the middle of the middle of the internal circuit board. Not rated for use with natural gas

The PX4600 specifies an accuracy of +/-0.25% FSO. But the thermal effects across the compensated temperature range, at full scale seem to add an additional 14%. That can't be right? 121°C x 0.036%/°C x 30 mV = 4.257 mV. 4.257 mV / 30 mV=14.19%.
Thank you for this inquire
see below
For calculating thermal effects:
Use 25°C for reference temperature.
Max. compensated temperature is 121°C.
Change in temperature is 121 -25 = 96°C.
Thermal effect is 0.036% FSO/°C. (Note: this is 0.00036 FSO/°C, using decimal equivalent of percentage.)
FSO = 30 mV.
Calculating for this change in temperature:
0.00036/°C x 96°C x 30mV = 1.0368 mV
1.0368 mV / 30 mV = 0.03456 or 3.456 %
Similarly for Min. compensated temperature of -55°C,
Change is temperature is 25 – (-55) = 80°C
Calculating for this change in temperature:
0.00036/°C x 80°C x 30mV = 0.864 mV
0.864 mV / 30 mV = 0.0288 or 2.88 %
Uncompensated silicon strain gages may have thermal errors of 10 to 20 %.
