Improved aerosol sensor testing
An aerosol detector test system (Fig. 2) comprises a vibrating mesh nebuliser 1 to generate an aerosol. The nebuliser may introduce aerosol into an aerosol line (7, Fig. 2) to which an aerosol sensor instrument may be connected. The nebuliser is used in testing and calibrating aerosol sensors/detect...

Summary: | An aerosol detector test system (Fig. 2) comprises a vibrating mesh nebuliser 1 to generate an aerosol. The nebuliser may introduce aerosol into an aerosol line (7, Fig. 2) to which an aerosol sensor instrument may be connected. The nebuliser is used in testing and calibrating aerosol sensors/detectors; the sensors/detectors may be for detecting hazardous chemical aerosols, e.g. chemical warfare agents. The nebuliser comprises a reservoir for liquid, a mesh/plate 2 comprising multiple perforations, and a driver 4 for vibrating the mesh/plate. The driver can provide a variable drive frequency, perhaps between 1 Hz and 100 kHz, to enable the mesh/plate to be vibrated at variable duty cycles, so that the nebuliser can deliver variable concentrations of aerosol. |
