HLD Sensor: Advanced Algorithm Leak & Thermal Conductivity Detection

Honeywell Hydrogen Leak Detection (HLD) Sensor utilizes the Honeywell advanced compensation algorithm to detect hydrogen leaks in different applications. This sensor features precision, reliability, and Thermal Conductivity Detection (TCD) technology, delivering lasting performance for applications that need a highly accurate solution without manual intervention for 10 years.

Advanced detection capabilities ensure the identification of hydrogen leakage of ≥50ppm, enabling this sensor to be used in many industries, such as automotive, residential power generators, and industrial safety equipment. When compared to catalytic beads, this sensor offers greater accuracy, extended sensor lifespan, and enhanced resistance to chemical poisoning. Honeywell HLD Sensor is typically adjacent to hydrogen storage tanks, hydrogen gas piping, fuel cells, and vehicle cabins.

Customization

The HLD Sensor may be customized to meet application needs, such as lightweight applications and having auxiliary output. Solutions may be tailored to exact specifications for improved time to market, lower total system costs, and enhanced reliability. For technical assistance, Honeywell provides global engineering and service support for your needs.
