Series AT2605 ATEX/IECEx Approved 605 Differential Pressure Indicating Transmitter
Series 605 in Flame-Proof Enclosure
CURRENTLY NOT AVAILABLE.
The ATEX/IECEx approved Series AT2605 Indicating Transmitter provides for both visual monitoring and electronic control of very low differential pressure in hazardous locations. The easily read dial gage is complimented by the two-wire, 4 to 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 to 20 mA control loop powered by a 10 to 35 VDC supply. Flame-proof enclosures are available in aluminum and can include a glass window for viewing process pressure on 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 keep IP66
rating (IP65 with option OPV, overpressure relief valve).
• 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.
Please see Series 605 for non-ATEX/IECEx approved.
