The popular Series AT22000 Magnehelic® Differential Pressure Gage is now available in a flame-proof ATEX enclosure with the new ATEX approved AT22000 Series. This gage can indicate positive, negative or differential pressures and is accurate within 2%.

Important notes for installation:
• Cables must be fitted through 1/2" NPT cable gland or ATEX/IECEx conduit (not supplied with instrument).
• Make sure after cabling to close tight cover and cable gland, in order to maintain IP66 rating.
• Open cover only after de-energizing instrument.


Attention: Check local safety rules and warnings on unit and manual for a correct use of the instrument in hazardous area.

• ATEX housing provides all the capabilities and value of the Magnehelic® in a flame & explosion proof enclosure
• Quick response to pressure changes means no delay in assessing critical situations
• Durable and rugged housing and high-quality components combined provides long-service life and minimized down-time
• High impact strength and high temperature rated for applications where hazardous environments exist
• Increased response time at low pressures with LD port configuration
