Series AT-605 ATEX/IECEx Approved Magnehelic® Differential Pressure Indicating Transmitter

Series 605 in Flameproof ATEX/IECEx Enclosure

The Series AT-605 ATEX/IECEx Approved Magnehelic® Differential Pressure Indicating Transmitter provides for both visual monitoring and electronic control of very low differential pressure in hazardous locations. An easy-to-read dial gage is complimented by the two-wire, 4-20 mA control signal utilizing the time-proven Dwyer® Magnehelic® gage mechanical design and Series 600 transmitter technology. The two-wire design simplifies any 4-20 mA control loop powered by a 10-35 VDC supply. Flameproof enclosures are available in aluminum and can include a glass window for viewing process pressure on the gage face.

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 areas.

Please see Series 605 for non-ATEX/IECEx approved.
