Catalog excerpts
ATI’s Series D12 gas transmitter line now includes a versatile Infrared system that can be configured for LEL or select toxic gases. The D12-IR utilizes a compact IR sensor in a corrosion resistant housing with sintered flame arrestor to meet hazardous area classification requirements, and is suitable for most plant environments. The D12-IR gas transmitter eliminates the poisoning problems inherent in catalytic bead sensors. While catalytic LEL sensors offer reliable service, the presence of silicon vapors, hydrogen sulfide, and halogenated hydrocarbons can quickly degrade sensor...

Features For Every Application • LCD Graphics Display: Gas concentrations are displayed in • Fail-safe Sensor Operation: Because the IR sensor is large, easy to read numbers. The display also provides alarm always in an active state, the transmitter continuously moni- indication and complete menus for setting up operating para- tors critical sensor functions and indicates any sensor prob- meters. A backlight is standard for good visibility in low light. lems, both on the display and via the analog output. • Internal Data Logger: Measured gas values are stored at • High Range Methane...
