HLS-440P Automotive Hydrogen Leak Sensor The HLS-440P automotive hydrogen sensor monitors hydrogen leakage concentrations of 0 - 10% in air. The design fulfills Zone 2 requirements according to ATEX 100a. The predicted concentration is transmitted to the host via the CAN bus interface or with PWM output. Type A The sensor shall measure the hydrogen concentration in high humidity conditions, e.g. in the exhaust of a fuel cell system, to ensure compliance with defined upper thresholds. Type B The sensor shall measure the hydrogen concentration under ambient humidity conditions, to ensure compliance with defined upper thresholds.
