DPG509

Supported Applications

The Omega DPG509 is an advanced digital pressure gauge designed for precise measurement of absolute, differential, and gauge pressures. The series features a user-friendly interface with four membrane key switches and a large backlit display to facilitate monitoring in various industrial settings.

• Pressure type capabilities include Absolute, Differential, and Gauge measurements.
• Data logging functionality is available via an optional Micro SD card for recording pressure data over time.

Operating Conditions & Performance

The DPG509 series delivers high-accuracy performance with specified accuracy classes of ±0.08% Full Scale Span or ±0.25% Full Scale Span, depending on the selected range and configuration. The gauge operates within an ambient temperature range of -17°C to 54°C (0°F to 130°F) and can be stored without batteries from -40°C to 82°C (-40°F to 180°F).

• Accuracy: ±0.08% Full Scale Span or ±0.25% Full Scale Span.
• Long Term Stability: ±0.3% Span/Year.
• Battery Life (Typical): 1,000 hours with no backlight usage.
• Pressure Cycles: Rated for 1 million cycles.
• Over Pressure Limit: 1.5 x rated pressure.

Configuration Options

The DPG509 series is highly configurable, offering over 40,000 possibilities to meet specific installation requirements. Key configuration dimensions include process connections, output signals, power sources, and menu complexity levels.

Housing & Environmental Protection

• Enclosure Material: Engineered Thermoplastic with an IP65 environmental rating.
• Display: 4-digit LCD with backlight and 25 mm (1") character height.
• Weight: 1.25 lbs.

Sensor & Wetted Parts

• Wetted Materials: Sensor wetted parts consist of 316L Stainless Steel with a Viton Seal.
• Minimum Resistance Between Transducer Body and any Wire: 100 MOhms @100 VDC.

Process Connections

The series supports multiple connection types available in male or female configurations:

• NPT: 1/4-18, 1/8-27.
• BSPP: 1/8 B, 1/4 B.
• Military Standard (MS33656-04): 7/16-20 UNF.

• Metric: M12 x 1.5.

Electrical Outputs & Power

The gauge supports various analog output signals and power configurations:

• Analog Output Options: None, 4 to 20 mA, 0 to 5 Vdc, 0 to 10 Vdc, or a combination of all three.
• Power Supply: Operates on 4 Alkaline AA Batteries (included) or DC Power through an M12 connection with battery backup.
• Cable: A 6' M12 connector cable is included with configurations featuring the DC power option.

Additional Options

• Data Logging: Supports Micro SD cards up to 32 Gb (8 Gb card included with data logging options).
• Protective Rubber Boot: Adds an additional layer of durability.
• Calibration Service: A configurable option for 5-point NIST traceable calibration.

Key Product Differences

The DPG509 series is distinguished by its menu complexity and accuracy levels. Models are available with either basic menu options only or advanced plus basic menu options, allowing users to select the level of functionality required for their application.

• Accuracy Tiers: The ±0.25% Full Scale Span accuracy applies to ranges such as 0 to 15 psi and 0 to 500 psi. The higher precision ±0.08% Full Scale Span is available for ranges including 30 to 1000 psi and 1500 to 5000 psi.
• Menu Complexity: Variants are offered with "basic menu options only" or "advanced plus basic menu options," affecting the depth of user configuration capabilities.
