Spectrex, among the world leaders in the development and implementation of optical flame and gas detection and suppression systems, has launched its unique Hydrogen Flame Detector, model 20/20SH.
As the hydrogen community moves towards commercialisation of their techniques, the emerging use of hydrogen for automotive transportation requires special safety measures for refilling stations, storage tanks and special hydrogen fuel cell handling facilities.
The new hydrogen detecting model is designed to address the needs of these and a wide range of industrial and commercial facilities that use hydrogen fuel cells, hydrogen gas generators and hydroxyfuels.
Most existing optical flame detectors are designed for detection of hydrocarbon flames and are based on the CO2 emissions: these cannot detect hydrogen flames that emit in the water vapour (H2O) band, with no emissions in the CO2 range. UV and some UV/IR optical flame detectors that can detect the hydrogen flame have a very limited detection range.
Therefore, the new product from Spectrex includes sensors which detect the main combustion product of hydrogen, water vapour. The optical sensors and filters are also manufactured to ensure the greatest degree of spectral matching to the radiant energy emitted by a hydrogen fire, and the lowest degree of matching to non-fire stimuli.
