Honeywell – HLD-111-111-001 The Hydrogen Leak Detector measures Hydrogen concentration in the air up to 40,000 PPM, and it is based on Thermal concavity with an input voltage between 8 to 36 V

Part of Honeywell's HLD Series Hydrogen Leak Detection Sensor range. 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 • Simpler Integration: Supports CAN and Analog (0-5V) Voltage interfaces • Thermal Conductivity base sense element • Fast response time: <2 seconds • Short Startup Time: <1 second • Hydrogen sensing range: 0% to 4% (CAN)/10% (Analog) • Operating Temperature Range: -40°C to 85°C (-40°F to 185°F) • 50 (CAN) or 1(Analog) H2 PPM resolution to detect low levels of H2 leakage • Resistant to chemical poisoning

OPERATING MODESThe sensor functions in the following operating modes: • ECO Mode: When the equipment is keyed off, the HLD Sensor can run in ECO mode to minimize power/current consumption. The sensor monitors and analyzes the air for Hydrogen leakage every 60 seconds. The sensor will communicate the Hydrogen level in the air during ECO mode if the analyzed air has a Hydrogen level greater than the calibrated threshold. Sensor output is provided to the equipment controller via the selected method of communication. • Continuous Mode: When the equipment is keyed on, the H2 leak detector is run in Continuous Mode. Hydrogen content in the surrounding air is reported to the system controller in 100 ms intervals.

DIFFERENTIATION• Accuracy: Temperature, pressure, and humidity are compensated to deliver accuracy over the specified operation range. • CORE TECHNOLOGY: TCD technology offers superior performance and is reliable in detecting hydrogen gas, even at low concentrations. • Integration: The HLD Sensor is designed to provide output using different methods, such as CAN and analog voltage output.Contact your Honeywell representative if you are interested in additional output methods.

VALUE TO CUSTOMERS• Accurate: Designed for precise H2 measurements 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.

APPLICATIONSThe HLD sensor is typically adjacent to the Hydrogen Storage Tank, Hydrogen Gas Piping, Fuel Cell, or Vehicle Cabin. The following are examples of Hydrogen applications: • Hydrogen Powered Material Handling Equipment• Hydrogen Powered Heavy Duty Trucks• Hydrogen Powered Buses• Hydrogen Power Generators• Hydrogen Powered Automobiles• Hydrogen Powered Construction Equipment• Hydrogen Powered Aircraft
