Differential Pressure Gauge Dwyer Magnehelic 2030 0-30 in.w.c.

Description

Product Overview

The Dwyer Magnehelic 2030 differential pressure gauge is engineered to deliver reliable, high‑resolution measurement of pressure differentials ranging from 0 to 30 inches water column (in w.c.). Constructed from robust materials, the gauge features a vertical diaphragm that remains stable under a wide range of operating conditions, ensuring consistent accuracy even in harsh industrial settings. The gauge incorporates 1/8″ female NPT high‑pressure and low‑pressure taps, duplicated on both the side and back, allowing flexible installation configurations. Its compact package dimensions of 5.8 × 5.3 × 3 inches and a weight of just 1.2 lb make it easy to mount on panels, enclosures, or handheld rigs without sacrificing performance.

Designed for air and non‑combustible gases, the Magnehelic 2030 can also be paired with a natural‑gas option when required, expanding its applicability across HVAC, process control, and environmental monitoring systems. The gauge operates within a temperature envelope of 20 °F to 140 °F (‑6.7 °C to 60 °C), providing stable readings despite ambient temperature fluctuations. Its clear, analog face with a 0‑30 in w.c. scale enables quick visual interpretation, while the durable glass and stainless‑steel housing protect the internal mechanism from corrosion and mechanical shock.

Usage

In commercial HVAC installations, the Magnehelic 2030 is commonly used to monitor static pressure across filters, coils, and ductwork, helping technicians verify proper airflow and detect blockages before they lead to system inefficiencies. The gauge’s ability to measure low differential pressures makes it ideal for balancing air‑handling units, ensuring that each zone receives the designed airflow volume. In process industries, the gauge monitors pressure drops across pipelines, valves, and instrumentation, providing critical data for maintaining safe operating conditions and optimizing fluid dynamics.

Because the gauge is compatible with both air and non‑combustible gases, it is frequently employed in clean‑room environments, laboratory exhaust systems, and gas‑handling facilities where precise pressure control is essential. Its vertical diaphragm orientation simplifies installation on vertical manifolds, and the duplicated NPT connections allow users to sample pressure from multiple points without additional fittings, reducing installation time and potential leak points.

Field technicians appreciate the gauge’s rugged construction and straightforward calibration process. The clear scale and robust pointer reduce reading errors, while the low‑maintenance design minimizes downtime. Whether mounted on a control panel, integrated into a portable test kit, or installed in a remote monitoring station, the Magnehelic 2030 delivers dependable performance that supports preventive maintenance programs and regulatory compliance.

FAQ

What is the recommended installation orientation for the gauge?

The gauge is designed for vertical diaphragm orientation, meaning the diaphragm should be positioned vertically for optimal performance. While other orientations are possible, they should be confirmed with Dwyer technical support to ensure accuracy is not compromised.

Can the gauge be used with natural gas?

Yes, the Magnehelic 2030 can be equipped with a natural‑gas option. This variant is specifically calibrated for natural‑gas applications and should be ordered with the appropriate option code to ensure proper compatibility.

How often should the gauge be calibrated?

For most industrial applications, an annual calibration is recommended to maintain measurement accuracy. However, environments with extreme temperature swings or high vibration may require more frequent calibration. Dwyer’s service network can perform on‑site calibrations to minimize downtime.

What are the temperature limits for operation?

The gauge operates reliably between 20 °F and 140 °F (‑6.7 °C to 60 °C). Operating outside this range may affect the diaphragm’s elasticity and the overall accuracy of the instrument.

Are replacement parts available?

Yes, Dwyer provides a full range of replacement components, including diaphragms, glass faces, and NPT fittings. Genuine parts ensure the gauge continues to meet its original specifications and performance standards.
