The Dwyer Series IS626 Pressure Transducer
convert pressure into a
standard 4-20 mA output signal. The Series IS626 can be used to accu-
rately measure compatible gases and liquids. Series IS626 full scale ac-
curacy is 0.25% (see specifications). Designed for industrial
environments with a NEMA 4X (IP66) housing, this transmitter resists
most effects of shock and vibration.
Intrinsic Safety Approval Classification
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 8th Edition, CAN/CSA C22.2 No. 60079-0:15 and
CAN/CSA C22.2 No. 60079-11:14.
