Supported Applications
The Omega PX180B series comprises miniature silicon/brass pressure transducers designed for general industrial and commercial applications. These OEM-style, compact units measure gage, vacuum, and compound pressures using micro-machined silicon technology.
- Gage Pressure: Ranges from 0 to 500 psi (0 to 34.5 bar).
- Vacuum: Ranges up to -14.7 psi (-1.0 bar).
- Compound Pressure: Combined vacuum and gage ranges such as -14.7 to 60 psi.
Operating Conditions & Performance
The series delivers a reference accuracy of ±0.3% FS maximum (including linearity, hysteresis, and repeatability) for the PX180B millivolt output models. The compensated temperature range is -25 to 75°C (-13 to 167°F), with an operating ambient temperature span of -40 to 80°C (-40 to 176°F). Process temperatures are rated from -40 to 100°C (-40 to 212°F) for the PX180B, while related series members (PX181B/PX182B) support process temperatures up to 125°C (257°F).
- Thermal Effects: ±2% FS maximum over compensated temperature range for both zero and span.
- Stability: Less than 0.25% FS per year.
- Mechanical Ratings: Shock rating of 30g; vibration resistance of 10G, 55 to 2000 Hz.
- Pressure Limits: Proof pressure is 2x Full Scale (750 psig for the 500 psi range); burst pressure is 3x FS or 750 psig, whichever is less.
Configuration Options
The PX180B series offers configurable output signals and material options across related model families (PX180B, PX181B, PX182B). The primary wetted materials for the brass-based models include Brass, Borosilicate, Silicon, RTV, and Epoxy. Stainless steel versions are available in the broader family documentation.
- Output Signals: Millivolt (0 to 50 mV or 0 to 100 mVdc), Voltage (1-5 VDC), and Current (4-20 mA).
- Electrical Connection: Options include a 36" cable with 24 AWG wire, DIN 43650 Form C connector, or an 18" shielded cable depending on the specific model.
- Housing Material: Aluminum, black anodized electronics housing.
- Process Connection: Standard connection is ¼ NPT male (some family documentation notes 1/8-27 NPT for related models).
Accessories
The series supports optional pressure snubbers to manage specific media conditions:
- PS-8E: For water or light oils.
- PS-8D: For dense liquids or oils.
- PS-8G: For gases and steam.
Key Product Differences
The series distinguishes models by output type, pressure range, and material composition. The PX180B designation specifically refers to the brass/millivolt (cable) configuration with a ¼ NPT male connection. Related variants include:
- PX181B: Brass housing with 5V voltage output.
- PX182B: Brass housing with 4-20 mA current output.
- PX480A/PX481A/PX482A: Stainless steel wetted materials available for higher pressure or corrosive service, offering millivolt, voltage, and current outputs respectively.
Model numbering follows the format PX . For example, PX180B-015GV denotes a 0 to 15 psi gage pressure transducer with millivolt output. Conductive media applications require tying "-Vin" to case potential for specific models (PX180B and PX182B).
