DPG1001

Supported Applications

The Omega DPG1001 Series is a family of high-accuracy digital pressure gauges designed for industrial applications requiring precise measurement with NIST certification. The series features rugged construction suitable for portable or fixed installations, utilizing 3½-digit LCD displays and extruded aluminum cases.

These instruments are specified for measuring all liquids and gases compatible with 316 SS wetted parts. Custom ranges are not available; the series is offered in standard gauge pressure configurations.

Operating Conditions & Performance

The DPG1001 Series delivers an accuracy of ±0.10% FSO or better, including linearity, hysteresis, and repeatability within ±1 least-significant digit. Temperature stability is rated at ±0.003% of span per °C (typical) and ±0.01% of span per °C (max). The compensated temperature range is 0 to 70°C (32 to 158°F).

• Operating Temperature: -20 to 85°C (-4 to 185°F)
• Storage Temperature: 0 to 70°C (-18 to 158°F) per specification table; broader range of -55 to 95°C (-67 to 203°F) noted in extracted attributes
• Response Time: 3 readings per second
• Pressure Limits: Minimum overpressure rating is 2x rated pressure; minimum burst pressure is 4x rated pressure.

The enclosure is splashproof with a polycarbonate cover and front/rear gaskets. The standard process connection is ¼-18 MNPT constructed of 316 SS.

Configuration Options

The series supports three distinct power configurations to accommodate different installation needs:

• Battery-Powered (DPG1001B): Operates on two 'AA' batteries providing up to 2500 hours of life typically. Features include auto shut-off after 5 minutes and LOBAT indication.
• Loop-Powered (DPG1001L): Provides a 4 to 20 mA output loop powered by 8 to 32 Vdc at the gauge with reverse polarity protection. Includes internal potentiometers for loop 4 mA and 20 mA calibration.
• AC/DC-Powered (DPG1001AD): Accepts 8 to 24 Vac 50/60 Hz or 9 to 32 Vdc with a maximum current draw of 5 mA. No output signal is provided on this model.

All models feature top-accessible, multiturn potentiometers for display zero/span adjustment within ±15% range (DPG1001B and DPG1001AD) or test calibration level from 0 to 100% range (DPG1001L). The electrical connection on the loop-powered model includes a 0.9 m (3') 2-conductor 22 AWG cable at the back of the gauge; battery and AC/DC models do not require this cable.

Standard Ranges

The series is available in standard ranges including: 0 to 5.00 psi, 0 to 15.00 psi, 0 to 100.0 psi, 0 to 500 psi, and 0 to 1000 psi gauge.

Key Product Differences

• DPG1001B: Battery-powered variant with no output signal; includes auto shut-off functionality. Weight is approximately 255 g (9 oz).
• DPG1001L: Loop-powered variant providing a 4 to 20 mA output loop and internal calibration potentiometers for the loop current.
• DPG1001AD: AC/DC powered variant with no output signal, designed for fixed installations where line power is available.

An optional wall-mount 115 Vac power supply (Model DPG1000-PS) is listed as an accessory. The series includes a NIST certificate and is made in the USA.
