Universal gas transmitter with HART output over 4-20 mA, compatible with Optima Plus and Searchline Excel infrared sensors

The XNX universal transmitter is the Honeywell Analytics gas detection platform designed to work with the widest range of sensors on a single device. This infrared (IR) personality version connects to external Searchpoint Optima Plus point infrared and Searchline Excel open-path sensors for hydrocarbon detection in potentially explosive atmospheres. It is used on oil and gas production platforms, onshore terminals, refineries, chemical and petrochemical plants, and liquefied natural gas terminals. It integrates with gas monitoring controllers, industry-standard PLCs, and SCADA systems via 4-20 mA, HART, Modbus, or Foundation Fieldbus.
