PX5500-MV

Supported Applications

The Omega PX5500/PXM5500 Series consists of high-performance thin film pressure transducers designed for testing, R&D/engineering test laboratories, functional test systems, production testing, product quality assurance, flight testing, gas turbine and engine test standards, ground support equipment, hydraulic systems, and custody transfer measurements. These solid-state devices feature a sputtered strain gage design engineered to provide high shock and vibration resistance with low drift.

Operating Conditions & Performance

The series offers measurement ranges from 0-15 to 0-10,000 psi for standard models and 0-1 to 0-600 bar for metric models. Accuracy is specified as ±0.10% FSO (BFSL) for ranges below 1000 psi and ±0.15% FSO for 1000 psi and above, based on a 5-point NIST calibration standard. Hysteresis and repeatability are both rated at ±0.025% FSO/°F.

Operating conditions span an ambient temperature range of -18 to 82°C (0 to 180°F) and a process temperature range of -54 to 150°C (-65 to 300°F). The transducers are compatible with gas, light oil, and dense liquid media. Wetted materials consist of 17-4 PH or 15-5 PH SS.

Pressure limits include a continuous pressure rating of 2 times rated pressure or 15,000 psi (whichever is less) and a burst pressure limit of 3 times rated pressure or 20,000 psi (whichever is less). Shock qualification meets the level of 100 g, 11 ms half sine wave without damage. Vibration performance at 35 g peak sinusoidal vibration from 10 Hz to 2000 Hz results in output not exceeding 0.04% FSO/g for the 15 psi range, decreasing to 0.003% FSO/g for 1000 psi and above.

Configuration Options

The PX5500/PXM5500 Series is configurable across pressure ports, electrical connections, ranges, units, output signals, and options. The overall dimensions are a maximum length of 74 mm (2.90 in) and a maximum diameter of 25.7 mm (1.01 in), with a weight not exceeding 200 g (7 oz).

Pressure Ports

• Standard: MS33656-4 or G¼B Male/Female for metric models.
• Available options include ¼-27 NPT Male, ¼-27 NPT Female, ¼-18 NPT Male, and ¼-18 NPT Female. Military connectors MS33656-4 and MS33649-4 are also supported.

Electrical Connections & Outputs

• Standard electrical connection is PTIH-10-6P (mating connector PTS06A-10-6S sold separately).
• Alternative connections include a mini DIN connector or an integral 0.6 m (2 ft) cable.
• Output signals available are mV/V, 0 to 5 V, and 4 to 20 mA.

Ranges & Units

• Standard models cover ranges from 15 psi up to 10K psi (e.g., 0-15, 0-25, 0-50... 0-10,000).
• Metric models cover ranges from 1.0 bar up to 600 bar.
• Pressure types include Absolute (A), Gage (G), and Sealed Gage (S).

Options & Accessories

• CAL11: 11-point calibration certificate available as an option.
• Pressure snubbers are offered for specific media types including Gas, Light Oil, and Dense Liquid in both NPT (PS-4G, PS-4E, PS-4D) and G¼B (PS-4G-MG, PS-4E-MG, PS-4D-MG) configurations.

Key Product Differences

The series is divided into two primary model families: the PX5500 for standard units and the PXM5500 for metric units. While both share similar performance characteristics, they differ in their default pressure port standards (MS33656-4 vs G¼B) and available range increments.

Output configurations vary by model selection; mV/V is a standard output option alongside 0 to 5 V and 4 to 20 mA. The series supports both Absolute, Gage, and Sealed Gage pressure types across the documented ranges.
