Supported Applications

The Omega DPG409 is a digital differential pressure gauge designed for washdown and marine applications. It incorporates a rugged enclosure suitable for environments requiring high durability, utilizing a precision micromachined silicon sensor with 316L stainless steel wetted parts.

Operating Conditions & Performance

The series delivers an accuracy of ±0.08% BSL (combined linearity, hysteresis, and repeatability) across measurement ranges from 0-10 inH₂O to 0-1000 psi (0-25 mbar to 0-70 bar). The device operates within an ambient temperature range of -18 to 66°C (0 to 150°F), with a storage temperature capability from -40 to 82°C (-40 to 180°F).

Performance specifications include:

Thermal Effects: Zero balance and span setting drift of ±1% span for ranges 10 inH₂O to 1 psi; ±0.5% span for ranges greater than 1 psi.
Long Term Stability: ±0.1% FS typical over one year.
Pressure Cycles: Minimum of 1 million cycles.
Response Time: User selectable from 0.38 to 30 sec (preset to 1/sec).

The gauge features a weatherproof enclosure rated NEMA 4X (IP65). Proof pressure ratings vary by range: 10 times range for the 10 inH₂O model; 6 times range for 1 psi; 4 times range for 2.5 to 750 psi; and 3 times range for the 1000 psi model.

Configuration Options

The DPG409 series is configurable across multiple pressure ranges, output signals, and connectivity options. The standard process connection is a ¼-18 NPT male thread. Wetted parts are constructed from 316L stainless steel.

Measurement Ranges

The series supports the following differential pressure spans:

0 to 10 inH₂O (0 to 25 mbar)
0 to 1 psi (0 to 70 mbar)
0 to 2.5, 5, 15, 30, 50, 100, 150, 250, 500, 750, and 1000 psi
Corresponding bar ranges from 0 to 1 up to 0 to 70 bar.

Analog Output & Power

The analog output is independently scalable via software selection or jumper settings. Available signals include:

0 to 5 Vdc (requires external power)
0 to 10 Vdc (requires external power)
4 to 20 mA (requires external 24 Vdc power supply)

The unit is powered by one included 3.6V lithium C cell battery with an 8.4 Ah capacity, providing up to 9 months of typical life.

Wireless & Connectivity Options

A wireless transmitter option (suffix "-W") sends readings to a remote location and includes charting and data logging software. Wireless models are restricted by transmission frequency regulations for use in the US, Canada, and Europe only. Compatible receivers include:

UWTC-REC1: 48-channel wireless receiver, USB powered.
UWTC-REC2: 48-channel wireless receiver with analog output.
UWTC-REC2-D: 48-channel wireless receiver with analog output and digital display.

A USB connection is provided for set-up only; the included cable facilitates configuration via software. The front panel includes functions to manually toggle backlighting, recall minimum/maximum values, zero the display, or clear min/max records.

Key Product Differences

The series distinguishes between standard models and those equipped with a wireless transmitter option. Standard model numbers follow the format DPG409-DWU (e.g., DPG409-1KDWU). Wireless variants add the suffix "-W" to the base model number (e.g., DPG409-1KDWU-W) and include two batteries instead of one.

Ordering requires specifying the analog output signal type: "V1" for 0 to 5 Vdc, "V2" for 0 to 10 Vdc, or "MA" for 4 to 20 mA. The enclosure finish is brushed 316 stainless steel with an ABS center gasket.
