The Dwyer Magnehelic® Differential Pressure Gauge 2215 is a precision instrument designed to measure differential pressure in air and non-combustible, compatible gases. With a measurement range of 0 to 15 psi, it offers accurate and reliable readings for various applications.
Key Features
- Measurement Range: 0 to 15 psi with minor divisions of 0.5 psi.
- Accuracy: ±2% of full scale at 70°F (21.1°C).
- Construction: Die-cast aluminum case and bezel with an acrylic cover, finished in gray to withstand a 168-hour salt spray corrosion test.
- Pressure Limits: -20 in Hg to 15 psig (-0.677 bar to 1.034 bar); optional higher pressure limits available.
- Temperature Limits: Operating range from 20°F to 140°F (-6.67°C to 60°C).
- Process Connections: 1/8″ female NPT duplicate high and low-pressure taps, with one pair on the side and one pair on the back.
- Enclosure Rating: IP67, ensuring resistance to dust and water ingress.
- Overpressure Protection: Relief plug opens at approximately 25 psig (1.72 bar) to prevent damage from overpressure.
