GAS DETECTOR CLOGGING DETECTION |
| 摘要 |
The present invention relates to a gas detector cell unit comprising a gas cell, the unit comprising an outer housing providing access to the gas outside through a protecting filter adapted to making gas cell safe for use in explosive environments, i.e. a sintered filter, and the unit comprising means for detecting reduction in the circulation through said protecting filter. |

1. A gas detector cell unit comprising a gas cell having a diffusive membrane, comprising an outer housing having a passage for gas outside the outer housing to pass therethrough, and a protecting filter in fluid communication with the passage, the unit comprising clogging detection means for detecting reduction in the circulation through the protecting filter by analyzing one of a transfer function and impulse response inside the filter. |
