The Dwyer SERIES IS626 Intrinsically Safe Pressure Transmitter can be used to accurately measure compatible gases and liquids compatible with its 316/316L stainless steel wetted parts. Series IS626 full-scale accuracy is 0.25%. Designed for industrial environments with a NEMA 4X (IP66) housing, this transmitter resists most effects of shock and vibration. Models are available with a 3´ cable or M-12 4 pin connection.

The IS626 is UL listed for use in Hazardous (Classied) Locations. The protection

method is by Intrinsic Safety, “ia”. It was investigated by UL under UL Standard 913 Sixth Edition and CSA Standard No. 157-92.

FEATURES/BENEFITS

• Exceptional accuracy for insuring tight-control and minimizing costly out of

specication conditions

• NEMA 4x rated enclosure provides protection in harsh environments permitting outdoor monitoring or in areas where dust and particulate matter exists

• Robust sensor provides shock and vibration resistance insuring stability in controlling
