Dwyer Magnehelic Gauge – Complete Guide
If you are looking for a reliable differential pressure measuring instrument, the Dwyer Magnehelic Gauge is one of the most trusted options in the market. This blog will explain everything about this gauge, including its price, dealers in India, catalogue, working principle, installation, calibration, and more.
What is a Dwyer Magnehelic Gauge?
The Dwyer Magnehelic Gauge is a type of differential pressure gauge used for measuring air and non-corrosive gases in various applications like clean rooms, HVAC systems, filters, and air handling units.
It is known for its accuracy, durability, and easy-to-read display, which is why many industrial setups, including MTC workshops, rely on it for pressure monitoring.
Working Principle of Magnehelic Gauge
The magnehelic gauge working principle is simple yet effective. It uses a diaphragm and magnet system to measure pressure differences.
- The diaphragm moves based on pressure changes.
- A magnet attached to the diaphragm moves a pointer on the dial.
- The pointer shows the pressure difference on a calibrated scale.
Pointer Table – Magnehelic Gauge Working Principle
| Component | Function |
|---|---|
| Diaphragm | Moves with a pressure difference |
| Magnet | Transfers the diaphragm movement to the pointer |
| Pointer/Dial | Displays differential pressure in a readable form |
| High/Low Pressure Ports | Connects to the system for measurement |
Applications of Dwyer Magnehelic Gauge
The Dwyer Magnehelic Gauge is used in many industries. Some examples include:
- HVAC systems – for filter monitoring and airflow measurement
- Clean rooms – to maintain differential pressure
- Air filters – to check pressure drop across filters
- Fume hoods and laboratories – to monitor airflow safety
- Industrial processes – to maintain pressure standards
