Figure 3: Hydrogen generators use HLD sensors for user safety
prevent hazards like gas buildup, fi re, or explosion; see Figure 3. Other industries, including in warehouse logistics, are also
tapping into the benefi ts of hydrogen power. For instance, hydrogen fuel cell forkliſt s are increasingly being used in warehouses due to fast refuelling capabilities and zero emissions. Workplace safety is ensured by placing HLD sensors in key locations and real-time monitoring for leaks around forkliſt s and fuelling stations; see Figure 4.
Sensitive, stable and reliable solutions Hydrogen is gaining popularity in many industries as a promising clean energy alternative for achieving sustainable energy goals due to its potential to reduce greenhouse gas emissions and reliance on fossil fuels.
Honeywell Sensing and Productivity Solutions supports this
transition with its HLD sensor series, mitigating safety concerns and building customer confi dence in hydrogen fuel cells. Its HLD series of sensors uses thermal conductivity detection techniques to deliver high sensitivity, stability and reliability for many applications across various industries, including automotive, transportation, industrial safety and residential power. T eir proprietary algorithm compensates for factors like temperature, pressure and humidity, ensuring accurate readings across a wide range of operating conditions. As a result, they can detect leaks as low as 50ppm, with accuracy of ±10%, within two seconds. Because of these properties, HLD sensors prevent false readings due to the presence of other environmental gases, like carbon monoxide or hydrocarbons.
