The Eaton MTL K1550 Gas Analysers, part of the Crouse-Hinds series, offer precise measurement of gas composition in binary or pseudo-binary mixtures, covering gases like hydrogen, carbon dioxide, argon, helium, and halogenated hydrocarbons such as Freons. Employing a katharometer sensor, the system gauges thermal conductivity variations within the gas components, enabling the measurement of a single constituent as long as its thermal conductivity differs from others. The sensor integrates a highly sensitive, maintenance-free element with low thermal capacity, ensuring high stability and eliminating the need for frequent calibration. Signal processing and temperature compensation, facilitated by a microprocessor, contribute to accuracy and an extended measurement range uncommon in this sensor category. The device, with certifications such as Ex II 2G EEx d IIB + H2 T6 and Ex II 1GD [EEx ia] IIC T6, operates within diverse temperature ranges and hazardous environments.
The analyzers accommodate a variety of gases, including hydrogen, helium, argon, carbon dioxide, krypton, neon, and Xenon. Featuring a robust design, the instrument offers a maintenance-free sensor, options for corrosive gas detection, non-depleting remote sensing, and fixed or variable compensation choices. Displayed on a large LCD, measured values, menu-driven configurations, and calibration prompts are easily accessible. With concentration alarms providing LED indication and volt-free changeover contacts, user-configurable settings for high and low thresholds enhance adaptability. The inclusion of a 4 to 20mA output, user-programmable span, and the flexibility to mount the sensor remotely or within the enclosure make the Eaton MTL K1550 an efficient and versatile solution for hazardous area gas analysis applications.
