Applications, Advantages, Configuration Details

H2scan’s HY-ALERTA^® 1600 Intrinsically Safe Area Hydrogen Monitor provides hydrogen-specific leak detection and measurement for hydrogen concentrations as low as 4000 ppm and can be scaled to any concentration up to 5% hydrogen by volume, a range representing 10% to 125% of hydrogen’s low flammability limit. The monitor is designed for either ceiling or wall mount and has an RS422 capability that extends an intrinsically safe interface from the hydrogen sensor to the controller to several hundred feet. H2scan’s hydrogen-specific sensor technology has no cross sensitivity to other combustible gases, thus eliminating false positive alarms and ensuring safety system reliability. An example application where this product and its benefits have been demonstrated is in the measurement of hydrogen in a Hydrogen-cooled Generator.
