Hw hld

The Hydrogen Leak Detector (HLD) Sensor uses the Honeywell advanced compensation algorithm to detect Hydrogen leaks in different applications. Designed with precision and reliability in mind, the HLD Sensor employs cutting-edge Thermal Conductivity Detection (TCD) technology to deliver lasting performance for many applications that require a highly accurate solution without manual intervention for ten years.

Its advanced detection capabilities ensure the identification of hydrogen leakage of 50 ppm or greater. Honeywell HLD Sensors can be utilized in many industries, such as automotive, industrial safety equipment, and residential power generators.

The incorporation of TCD technology in the HLD sensor offers several key advantages over catalytic beads. These benefits include greater accuracy, extended sensor lifespan, and enhanced resistance to chemical poisoning. With these advantages, the HLD sensor gives users the confidence that both lives and assets are well-protected.

Features:

  • High accuracy
  • CAN communication protocol (available) and voltage reading output (coming soon)
  • Thermal conductivity base sense element
  • Fast response time: <2 seconds
  • Short startup time: <1 second
  • Hydrogen sensing range: 0 % to 4 %
  • Operating temperature range: -40°C to 85°C [-40°F to 185°F]
  • 50 H2 ppm resolution to detect low levels of H2 leakage
  • Resistant to chemical poisoning

Applications:
The HLD sensor is typically adjacent to the hydrogen storage tank, hydrogen gas piping, fuel cell, or vehicle cabin.

  • Hydrogen-powered heavy-duty trucks
  • Hydrogen-powered buses
  • Hydrogen-power generators
  • Hydrogen-powered automobiles
  • Hydrogen-powered construction equipment
  • Hydrogen-powered aircraft

Value to Customers:

  • Accurate: Designed for precise H2measurements to improve safety, allowing enhanced protection of assets and life
  • Reliable: TCD technology usage enables the customer to reduce downtime by eliminating false positives
  • Packaging: The IP67 seal allows the use of HLD even in numerous applications
