Dwyer Series DPG Digital Pressure Gage
Product Introduction
The Dwyer Series DPG Digital Pressure Gage is a high-accuracy measuring instrument designed to replace outdated analog gauges. Available with ±0.25% or ±0.5% full-scale accuracy, it features a 4-digit backlit display that eliminates parallax errors for precise readings. Housed in a NEMA 4X (IP66) aluminum enclosure, the gage is battery-powered with an auto-shutoff function (2000-hour battery life) and offers selectable engineering units, making it ideal for industrial pressure monitoring in harsh environments.
Product Features
High Accuracy:
±0.25% FS (DPG-100 series) or ±0.5% FS (DPG-000 series) for reliable measurements.
Includes linearity, hysteresis, and repeatability at 70°F (21°C).
Parallax-Free Display:
4-digit backlit LCD (0.425" H digits) for clear readings in low-light conditions.
Eliminates reading errors common in analog gauges.
Versatile Range & Units:
Models cover -14.70 psi to 5000 psi, with selectable units (psi, kg/cm², bar, kPa, etc.).
E.g., DPG-105 supports 0–100 psi with 11 engineering units.
Rugged Construction:
NEMA 4X (IP66) aluminum housing with polycarbonate cover, resistant to dust and water jets.
Wetted materials: Type 316L stainless steel for corrosion resistance.
Battery Efficiency:
2x AAA batteries (2000-hour life, 60 hours continuous use).
Auto-shutoff (60 minutes) and low-battery indicator to conserve power.
Easy Operation:
Push-button zero/tare, peak/valley tracking, and unit conversion.
Simple 4-button keypad, no complex menus.
Safety Approvals:
CE certified; FM approval for intrinsic safety (DPG-100 series) in hazardous areas (Class I, Div 1, Groups A-D).
