1. Introduction to the Dwyer 2000-300MM Differential Pressure Gauge
The 2000-300MM is a mechanical differential pressure gauge from Dwyer Instruments (USA), part of the well-known Magnehelic® series. It is designed to measure pressure differences between two points in a system and is widely used in HVAC systems, cleanrooms, pharmaceutical plants, fume hoods, and more.

With a measuring range of 0–300 mmH₂O, this model is ideal for low-pressure applications requiring high sensitivity and fast, accurate response.

3. Real-World Applications of the 2000-300MM Differential Pressure Gauge
The 2000-300MM is commonly used in systems that require accurate and continuous pressure monitoring:

  • Cleanrooms and pharmaceutical plants: Monitors pressure differences between clean zones to ensure GMP compliance.
  • Fume hoods and air showers: Ensures filters are operating efficiently to protect user health.
  • HVAC systems (AHU – FCU): Measures pressure drop across air filters to monitor performance and issue alerts when filters need replacement.
  • Laboratories and hospitals: Maintains proper airflow direction using positive or negative pressure zones.
  • Industrial facilities: Measures pressure in compressed air systems, suction lines, and mechanical rooms.

4. Advantages of the Dwyer 2000-300MM Gauge

  • High accuracy
    With a margin of error of only ±2%, the device delivers stable and reliable readings even in mildly vibrating environments.

  • Mechanical design, no power supply needed
    Operates based on Dwyer’s Magnehelic® magnetic force principle, requiring no electrical power – cost-effective and easy to use.

  • Flexible installation
    Compact size; can be mounted directly on a control panel or wall. Standard 1/8” NPT ports make it easy to connect to pressure tubing.

  • Easy to read and operate
    Large, clear display with smooth, responsive needle. Optional accessories available: mounting bracket, silicone tubing, contact alarm module.

  • Durable and corrosion-resistant
    Epoxy-coated aluminum casing resists oxidation and harsh environments, ensuring long-term use.

5. Installation Guide for the 2000-300MM Differential Pressure Gauge
Proper installation is key to stable and long-lasting operation:

  • Step 1: Select installation location
    Avoid places with excessive vibration or extreme heat.
    Can be wall-mounted or installed on a control panel (using Dwyer standard mounting kits).

  • Step 2: Connect pressure tubing
    HIGH (+) port: Connect to the higher-pressure side.
    LOW (–) port: Connect to the lower-pressure side.
    Use flexible pressure tubing. Avoid sharp bends or clogs.

  • Step 3: Check for leaks
    Ensure there are no leaks at connection points.
    Use heat-resistant sealing tape on threads to improve airtightness.
