HPS-100 www.ams.com/Hydrogen-Sensors HPS-100 – Hydrogen Process 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 HPS-100 Hydrogen Process Sensor is an accurate, fast responding sensor designed for installation in harsh environments such as fuel cells, for example. The sensor will measure hydrogen in the range of 0–100% and will function up to 3 bar(a). The HPS-100 Hydrogen Process 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 HPS-100 Specifications Target gas Concentration range Accuracy Resolution Hydrogen 0–100% H 2 in nitrogen ±2% vol. typical ±0.5% vol. 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 < 1% typical operation. In addition, a short-start up time enables an intermittant mode of operation that minimizes current current consumption better. The HPS-100 Hydrogen Process Sensor will provide hydrogen detection and measurement for applications where conditions are harsh. With an IP6K9K rating and designed towards ATEX 100a zone 2, this sensor can be installed almost anywhere.
