IR 29E Methane Transmitter

GfG Instrumentation, 2901-09-007, IR 29E Methane Transmitter, No Display, ModbusUnlike 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.Acetylene, alcohols*, CO2 , fuel vapors**, saturated hydrocarbons***, unsaturated VOCs****Features:ATEX: II II 2G Ex eb mb ib [ib] IIC T4 GbPatented infrared technology (NDIR)Temperature, moisture and pressure compensationMaintenance and service-friendly4-20 mA, linear or digital (Modbus interface)Response Time:t 90 ≈ 35-50 secondsAmbient Temperature:Operation: -4°F to +131°FStorage: -13°F to +131°FHousing Protection:IP 67V4A Stainless steel with polycarbonateHumidity:0 to 95% r.h. non-condensingOutput Signal:4-20 mAPower Supply:15 to 30 V DC* Alcohols such as methanol, ethanol, isopropanol, etc...** Fuel vapors such as diesel, jet fuel, gasoline, etc...*** Saturated hydrocarbons such as methane, propane, butane, pentane, nonance, etc...**** Unsaturated VOCs such as MEK, toluene, butadiene, etc.
