Series IS626 Intrinsically Safe Pressure Transmitter
For Use In Hazardous Locations
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 (Classified) 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.
NIST CALIBRATION available in Product Configurator.
