Comparing Dwyer SERIES 2000 and SERIES 2300 Differential Pressure Gauges

Comparing Dwyer SERIES 2000 and SERIES 2300 Differential Pressure Gauges – Which Is Best for Your HVAC System?

Posted on: 19/06/2025

In HVAC systems and cleanrooms, differential pressure sensors play a critical role in monitoring airflow and pressure to ensure efficiency and air quality.

Dwyer Instruments, a trusted U.S. brand, offers a range of high-quality pressure sensors—among them, the SERIES 2000 and SERIES 2300 are the most commonly used.

So, what’s the difference between the two? Which one is right for your application?

Let DLK, Dwyer’s official distributor in Vietnam, help you compare and decide.

1. Overview of Dwyer SERIES 2000

Mechanical differential pressure gauge with no need for electrical power
Also known as the Magnehelic® Gauge, it uses a magnetic mechanism and Bourdon tube
Simple to operate, with clear analog needle display
Wide range of measurements: from 0–60 Pa up to 0–30 psi
Applications: Cleanrooms, hospitals, air filtration systems, fan pressure monitoring

2. Overview of Dwyer SERIES 2300

An upgraded version of the SERIES 2000, with added analog output (4-20mA or 0-10V)
Combines the same mechanical system with integrated electronics
Allows local display via analog needle and remote data transmission to automation systems
Applications: Advanced HVAC systems, SCADA, BMS, and highly automated facilities

3. Detailed Comparison: SERIES 2000 vs SERIES 2300

Feature	SERIES 2000	SERIES 2300
Power Requirement	No	Requires power for signal output
Display	Analog needle	Analog needle + signal output
Output Signal	None	4-20mA or 0-10V
Integration	Standalone	SCADA/BMS compatible
Data Logging	Not supported	Supported via connected systems
Cost	More budget-friendly	Higher investment, more features
Ideal Use Case	Simple, local monitoring	Smart, integrated building systems

4. Which One Should You Choose?

Go with the SERIES 2000 if you:

Need a simple solution for local pressure monitoring
Do not require remote data integration
Want to optimize costs for basic HVAC setups

Choose the SERIES 2300 if you:

Need both local display and remote output
Plan to integrate with a BMS or SCADA system
Want to track and analyze pressure data for optimization
