HLS-442

Automotive Hydrogen Leak Sensor

The HLS-442 automotive hydrogen leak sensor monitors

hydrogen concentrations of 0 – 4.4% in air. The sensor is a leak

sensor developed in accordance to IEC 61508 (SIL2) and

explosion protected according to ATEX 100a. The predicted

concentration is transmitted to the host via the CAN bus

interface. HLS-442 utilizes self-calibration that is performed

automatically when operated in air with normal hydrogen

concentration. Therefore, the HLS-442 should not continuously

be operated in elevated background levels of

hydrogen.

Ordering Information and Content Guide appear at end of

datasheet.
