Product Description

Dwyer 2000 Series 0–3 kPa Magnehelic Differential Pressure Gauge 

The Dwyer 2000 Series 0–3 kPa Magnehelic Differential Pressure Gauge is a precision-engineered, mechanical instrument designed for reliable and accurate measurement of low differential pressure in industrial, commercial, and HVAC applications. Renowned for its durability, simplicity, and visual clarity, the Magnehelic gauge has become an industry standard since its introduction by Dwyer Instruments, Inc., a leader in pressure measurement solutions. This 0–3 kPa model is ideal for monitoring pressure differences across air filters, fan and blower performance, furnace efficiency, and cleanroom environments, where maintaining optimal airflow and pressure balance is critical. Its unique design eliminates the need for electrical power, ensuring uninterrupted operation in remote or hazardous locations.

At its core, the Magnehelic gauge operates on a patented magnetic movement principle. It features a stationary magnet attached to a flexible diaphragm, which deflects proportionally to the applied differential pressure. The diaphragm's motion is transmitted to a rotary magnet via magnetic coupling, driving the pointer across a calibrated scale. This mechanical design provides immediate, analog pressure readings without requiring batteries, external power, or complex electronics. The 0–3 kPa range is particularly suited for low-pressure HVAC systems, where detecting minor pressure imbalances in ventilation ducts or filter clogging is essential for energy efficiency and system longevity. The gauge's high overrange capability—up to 10 times the full-scale value—ensures resilience against accidental pressure spikes, minimizing damage and downtime.

The gauge's construction emphasizes durability and environmental adaptability. Housed in a lightweight, corrosion-resistant aluminum case with a polycarbonate window, it withstands harsh conditions, including vibration, moisture, and temperature fluctuations (-40°C to +66°C). The internal components, including the diaphragm and magnetic linkage, are engineered from non-magnetic, anti-corrosive materials, ensuring compatibility with non-corrosive gases and air systems. Its compact size (85 mm diameter) and panel-mount design allow easy integration into control panels, equipment housings, or field installations. 

The 0–3 kPa Magnehelic gauge excels in versatility, accommodating a wide range of connection options and installation configurations. Pressure connections are typically made via two 1/8-inch NPT tapped ports on the rear of the case, allowing easy attachment to tubing or piping systems. The gauge can be mounted in any orientation without affecting accuracy, and its self-contained design eliminates the need for external amplifiers or transmitters. For applications involving viscous, dirty, or particulate-laden media, the gauge can be paired with remote mounting accessories or isolation valves to protect the internal components while maintaining measurement integrity.

Safety and compliance are integral to the Magnehelic gauge's design. It meets global industry standards, including CE, FM, and CSA certifications, ensuring suitability for use in hazardous locations (Class I, Div. 2; Class II, Div. 2). Its intrinsic safety and lack of electrical components make it ideal for explosive atmospheres or environments where sparks or electrical interference could pose risks. Additionally, the gauge complies with ASME B40.7 for pressure gauge accuracy and durability, reinforcing its reliability in critical processes.

Common applications for the 2000 Series Magnehelic gauge span across industries. In HVAC systems, it monitors air filter efficiency by detecting pressure drops across filtration units, signaling when replacement is needed. In cleanrooms and laboratories, it ensures proper airflow directionality by measuring pressure differentials between controlled zones. In industrial settings, it verifies the performance of dust collection systems, combustion airflows, and oven pressurization. Its ability to provide real-time, visual feedback without reliance on digital networks makes it a trusted tool for field technicians, maintenance crews, and system operators.

Maintenance requirements for the Magnehelic gauge are minimal due to its robust mechanical design. With no moving parts subject to wear and no electronic components to degrade, it offers decades of service with periodic calibration checks. The gauge can be recalibrated in the field using reference instruments or returned to Dwyer's certified calibration lab for traceable adjustments.
