GfG Instrumentation, 2901-50-004, IR 29I Carbon Dioxide Transmitter, No Display
Acetylene, alcohols*, CO2 , fuel vapors**, saturated hydrocarbons***, unsaturated VOCs****
The IR 29 i is the first intrinsically safe IR gas transmitter with patented GfG 4-beam 4-wavelength technology. Because the IR 29 i is intrinsically safe, there is no need to run transmitter cabling through expensive explosion proof conduit.
The IR 29 i is the first IR gas transmitter that can be installed and used in “Ex Zone 0” hazardous locations in which ignitable concentrations of combustible gas or vapor are assumed to be present at all times. Use of the SB1 safety barrier protects the ATEX Certified system from the possibility of the release of energy that could be the cause of ignition.
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.
