Honeywell HLD Series: Hydrogen Leak Detection Sensor

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
