Supported Applications
The Omega PX51/PXM51 Series consists of heavy-duty industrial pressure transmitters designed for harsh environments. These units feature rugged thick film sensing elements and all stainless steel construction with a sealed SS case to protect internal components. The series is engineered for measuring gas, liquid, and dense liquid media.
Available configurations include Imperial models (PX51) ranging from 0-10 psi to 0-30,000 psi, and Metric models (PXM51) ranging from 0-0.7 bar to 0-400 bar. The series supports Gage Pressure, Sealed Gage Pressure, and Absolute Pressure measurements.
Operating Conditions & Performance
The PX51/PXM51 Series operates within an ambient temperature range of -40 to 104°C (-40 to 220°F). The compensated temperature range is specified as 16 to 71°C (60 to 160°F).
- Accuracy: ±0.25% FS
- Hysteresis: ±0.25% FS
- Repeatability: ±0.25% FS
- Zero Shift: 0.005%FS/°F
- Span Shift: 0.003% Reading/°F
- Proof Pressure: 150%
- Burst Pressure: 300%
All models include a 5-point NIST traceable calibration and comply with EN 61326-1:2006, EN 61326-2-3:2006 Industrial levels. The wetted material is specified as 17-4 Stainless Steel.
Configuration Options
The series offers extensive configurability across pressure ports, electrical connections, output signals, and special options to accommodate diverse installation requirements.
Pressure Ports & Connections
- PX51 (Imperial): ¼-18 NPT-M, ¼-18 NPT-F, Dual ½-14 NPT external / ¼-18 NPT internal, ¼-20 UNF-F, ¼-20 UNF-M, and ¼ HP Tube Fitting (for ranges ≥10,000 psi).
- PXM51 (Metric): G¼B Male and G¼B Female.
Electrical Connections & Outputs
The series supports multiple electrical termination styles including a 3 m (10') pigtail with ½ NPT conduit, PTIH-10-6P twist-lock 6-pin connector, M12 connector, mini-DIN connector, and submersible waterproof cable with ½ NPT conduit.
Output signals are available in:
- 4 to 20 mA
- 0 to 5 Vdc
- 0 to 10 Vdc
The power supply requirement is 10 to 32 Vdc max. Note that for 0 to 5 Vdc and 0 to 10 Vdc versions, OUTPUT (-) is tied to SUPPLY (-).
Options & Accessories
- Potentiometers: Standard on most models; add 'NP' suffix for No Potentiometers.
- Mating Connector: PT06F10-6S (sold separately) required for the twist-lock connector option.
- Pressure Snubbers: PS-4G (Gas), PS-4E (Lt Oil), PS-4D (Dense Lq), and magnetic versions PS-4G-MG, PS-4E-MG, PS-4D-MG are available.
Key Product Differences
The series is divided into two primary model families based on unit systems:
- PX51 Series (Imperial): Configured with ranges in psi. High-pressure models from 0-10,000 to 0-30,000 psi utilize the 'S' pressure port code for a ¼ HP Tube Fitting.
- PXM51 Series (Metric): Configured with ranges in bar. Pressure ports are designated as G¼B Male or Female.
Pressure reference types are indicated by suffixes: 'G' for Gage, 'SG' for Sealed Gage, and 'A' for Absolute. Electrical connection codes vary between the two series to reflect their specific port geometries (e.g., PX51 uses C/D/T/K/J/S while PXM51 uses MA/MB/MC/MD).

Hello, I am looking for a pressure transducer with a range of 0psi - 30,000psi and that can take greater than 1 pressure sample per second. Do you guys have anything that can do this?
The PX51 Series transducer response time to a signal change of 1 to 2 milliseconds so they should work in your application.

How much power does this transducer use?
Hello, nominal current draw is 20 mA typically, but it really depends on the model you are looking at. Kindly email the full model number you are looking at to pressure@omega.com, we can provide the exact current draw

warranty how many years ?
It is 1 year warranty.

1) What is the supply voltage of the PX51 Series transducer? 2) Also, what does the output of this transducer look like? To explain further, does a specific output voltage (like 3.3V) correspond to a specific pressure (like 3.3V goes to 324psi)?
Power supply for the 4 to 20mA/ 0 to 5VDC versions is 10 to 32VDC. the 0 to 10VDC version requires 16 to 32VDC power. The output is a linear response over the pressure range of the unit. A 0 to 500 PSI range sensor with a 0 to 5VDC output would give a 3.24VDC output at 324 PSI

I am looking at the 0 – 5 volt units. What is the actual operating voltage range - are they 0.0 volts for 0 psi and 5.0 volts for the maximum rated pressure of the transducer? Or Are they 0.5 volts for 0 psi and 4.5 volts for the maximum rated pressure of
The output of this pressure transducer is 0.0 to 5.0 VDC across it's calibrated pressure range

Hi, i am working with gas injection core flooding equipment, and we will be working at P of about 600 bar. The working temperature will be around 90 C. Do you have a pressure transducer with USB connection which would cover that range? Thank you
The best fit for your application would be the PX51-USBH series industrial transducers with high speed USB output. 600 Bar is equivalent to about 8700 psi so the best range for you would be the 10,000 psig range, model number PX51S-10KG-USBH. Pressure range is 10,000 psi, but you can select bar as your display units in the free software which you download from our website. Maximum operating temperature is 85C and the pressure fitting is an Autoclave F250C female 1/4" high pressure tube fitting.
The lead time is 8 weeks. Our tech support has also sent you the spec sheet for further reference. Please contact our Tech Support if you need any further assistance with your application. Thanks!

Is PX51CGW-200G5V pressure sensor IP rated ? as I could not see any information about IP rating in the Datasheet
Thank you for your question, it is IP67 rated.
