PX610

Supported Applications

The Omega PX610 series consists of subminiature millivolt output pressure transducers designed for accurate measurements in restricted locations. The unitized stainless steel diaphragm and sidewalls provide ruggedness while allowing thin construction to measure low pressures, including a few inches of water. These flush diaphragm transducers are configured with 7/16-20 UNF threads for industrial environments.

Media compatibility is defined by the seal configuration:

• Welded Diaphragm: Water, high moisture areas, and corrosive fluids (prevents moisture penetration to strain gages).
• Epoxy Seals: Air and nonconductor fluids.

The series supports both Gage Pressure and Absolute Pressure measurement types across the documented range envelope.

Operating Conditions & Performance

Performance specifications are defined by pressure ranges, temperature limits, and electrical characteristics. The PX610 offers a broad selection of gage and absolute pressure ranges:

• Gage Pressure Ranges (psig): 0 to 50, 0 to 100, 0 to 150, 0 to 200, 0 to 300, 0 to 500, 0 to 1000, 0 to 2500, 0 to 5000, 0 to 10,000, and 0 to 15,000.
• Absolute Pressure Ranges (psia): 0 to 50 and 0 to 100.

The transducers operate within a compensated temperature range of 16 to 71°C (60 to 160°F) and an operable process temperature range of -54 to 121°C (-65 to 250°F). Accuracy is specified as ±1% full scale BFSL (linearity and hysteresis combined), with repeatability at ±0.1% FS.

Electrical performance requires a 5 Vdc excitation voltage. Output sensitivity varies by range: 0.1 mV/PSI nominal for ranges ≤100 PSI, and 2 mV/V nominal for ranges >100 PSI. Input impedance is 350 Ω with an output resistance of 350 Ω.

Pressure limits include a proof pressure rating of 150% range and a burst pressure defined as the lesser of 400% range or 30,000 psi max.

Configuration Options

The PX610 series is configurable across multiple dimensions including measurement type, pressure range, output sensitivity, and sealing method. The following capabilities are available within the documented envelope:

• Housing & Wetted Materials: 17-4 PH stainless steel body and diaphragm.
• Process Connection: 7/16-20 UNF thread (flush diaphragm).
• Electrical Connector: PT06F10-6S-R Twist-Lock connector interface (sold separately as accessory).
• O-ring Options: BUNA-N (black) for normal operating temperatures; FKM and Polyvinyl options available.
• Approvals & Certifications: NIST Standard, CE, RoHS. Units include 5-point NIST-traceable calibration.

The series supports various pressure ranges from low-pressure applications (a few inches of water) up to high-pressure industrial requirements (15,000 psig). Model numbers follow the format PX610-AV or PX610-GV.

Key Product Differences

The primary distinction within the series is between Gage Pressure and Absolute Pressure models, indicated by the suffix in the model number (e.g., GV for gage, AV for absolute). Output sensitivity varies based on the selected pressure range: lower ranges (≤100 PSI) utilize a 0.1 mV/PSI nominal output, while higher ranges (>100 PSI) provide a 2 mV/V nominal output.

Sealing configurations differ by application media; welded diaphragms are specified for water and corrosive fluids to ensure hermetic sealing, whereas epoxy seals are utilized for air and nonconductor fluid applications. The series is available in multiple pressure ranges up to 15,000 psig (1034 bar), with specific model numbers assigned to each range increment.
