HLS-440P www.ams.com/Hydrogen-Sensors HLS-440P – Hydrogen Leak Sensor -Fast and highly selective -Low power and flexible packaging -Tough and resistant We provide innovative analog solutions to the most challenging applications in sensor and sensor interfaces, power management, and wireless. General Description The ams HLS-440P Hydrogen Leak Sensor is an accurate, fast responding sensor designed for installation in harsh environments such as fuel cell exhausts. The sensor will measure hydrogen in the range of 0-10% in air or nitrogen. The HLS-440P Hydrogen Leak Sensor features reduced power consumption, provides increased packaging flexibility, and includes a CAN interface with a standard MQS four-pin connector. Self-testing at start up and advanced error handling ensure reliable HLS-440P Specifications Target gas Concentration range Accuracy Resolution Hydrogen 0–10% H 2 in air or nitrogen ±0.5% vol. typical 500 ppm Speed of response (t90) < 5 seconds Speed of recovery < 5 seconds Cross-sensitivity Start-up time Self test/Error handling Explosion proof No detection towards HC, H2S, N2, CO, CO 2, NOx Humidity influence < 0.5% typical operation. In addition, a short-start up time enables an intermittant mode of operation that minimizes current consumption better. The HLS-440P Hydrogen Leak Sensor will provide hydrogen detection and measurement for applications where conditions are harsh. With an IP6K9 rating and designed towards ATEX 100a zone 2, this sensor can be installed almost anywhere.
