GfG Instrumentation 2901-21-007 IR 29E Acetylene Transmitter

GfG Instrumentation, 2901-21-007, IR 29E Acetylene Transmitter, No Display, 4-20mA

Unlike traditional LEL sensors, IR 29 transmitters do not need the presence of oxygen to detect gas. Since they are not affected by sensor poisons they don’t require periodic adjustment to make up for lost sensitivity. The IR 29 continuously monitors its functions for proper performance, and can even identify and communicate required service procedures.
