The Dwyer 2002D Magnehelic® gage is an industry-standard precision instrument designed for quick and accurate measurement of low air and non-corrosive gas pressures. It is primarily utilized in industrial applications for monitoring fan and blower pressures, filter resistance, air velocity, furnace draft, and pressure drop across various components.
Key Specifications and Features:
– Operating Principle: Utilizes Dwyer’s simple, frictionless Magnehelic® gage movement for reliable and immediate pressure indication.
– Measurement Capability: Accurately indicates positive, negative (vacuum), or differential pressures of air and compatible non-corrosive gases.
– High Accuracy: The HA (High Accuracy) option, as found in the 2002D (HA889) model, delivers precision measurement within 1% of full-scale accuracy.
– Robust Design: Engineered to resist shock, vibration, and over-pressures, ensuring sustained performance in demanding industrial environments.
– Environmental Rating: Weatherproof to IP67 standards, offering protection against dust and temporary immersion in water.
– Clear Display: Features an easy-to-read 4 inch (10.16 cm) white dial complemented by a high-visibility red-tipped pointer.
– Installation Flexibility: Supports versatile mounting options, including both flush and surface installations.
– User Accessibility: Equipped with an easily accessible zero adjustment mechanism for convenient calibration.
– Pressure Limits: Standard operational pressure limits range from 20 in Hg vacuum to 15 psig (‑0.677 bar to 1.034 bar), with optional configurations extending to 35 psig (2.41 bar) for MP (Medium Pressure) and 80 psig (5.52 bar) for HP (High Pressure) applications.
