DPG280

Supported Applications

The Omega DPG280 series consists of advanced digital pressure gauges designed for measuring gauge pressure and negative gauge pressure. These units are engineered to monitor gasses and liquids that are non-corrosive and compatible with 304 stainless steel wetted materials.

Operating Conditions & Performance

The DPG280 series operates within an ambient temperature range of -20°C-70°C, with a compensation temperature range of 0-60°C. Accuracy is specified as ±0.4%FS or ±0.2%FS depending on the configuration, and long-term stability is rated at 0.25 %Fs/year.

Overload capacity varies by pressure rating: ranges below 40Mpa support Range*150%, while ranges above 40Mpa support Range*120%. The series features a 4-digit LCD screen with a bright white backlight and includes visual indicators for battery level, communication status, and percentage of full-scale pressure usage.

Key Performance Specifications

• Measurement Type: Gauge pressure, Negative gauge pressure
• Data Logging Capacity: Up to 10,000 points stored in EEPROM
• Sampling Rate: Adjustable from three times per second to three times every hour
• Power Supply: 3V (2 AAA batteries)
• Electromagnetic Compatibility: Anti-EMI Design, EN61326

Configuration Options

The DPG280 series offers configurable pressure units including kPa, PSI, kg/cm², Bar, MPa, mmHg, and Torr. Units feature a zero clearing function accessible via the keypad (press for 4 seconds) and include peak value tracking.

Physical Construction & Connections

• Housing Material: 304 Stainless Steel shell with 304SS connection material
• Process Connection: 1/4-18NPT Male
• Dimensions: 46 mm width, 125 mm height, and 80 mm depth
• Data Interface: USB output with included software for data retrieval; a special USB-line is provided in the package box.

User Interface & Display Features

• LCD display shows pressure units, MAX/MIN values, battery level (0% to 100%), and communication signs.
• Error codes displayed include E-E for abnormal sensor communication or damage, E-H for current pressure over range use or sensor damage, and P-C/r-03 for calibration procedures.
• Buttons control Power, Unit switching, Backlight (short press to toggle; long press to keep on), and Zero clearing.

Key Product Differences

The series is available in multiple pressure ranges indicated by model suffixes such as -005G, -1.0KG, -300A, and others, covering various measurement spans referenced to a selection table not included in the primary documentation.

Specific variants include models with different range codes (e.g., DPG280-005CG vs. DPG280-V015G) which correspond to specific pressure limits and unit configurations. The series is noted as a recommended alternative to the DPG4000 Series.

Installation notes specify that units should be installed without power, using a suitable wrench for the threaded connection, followed by zero clearing after installation. Battery replacement requires removing four screws and prying off the lid at designated slots; force must not be applied to the keypad area during reassembly.
