Abstract
This invention concerns the measurement of particle size of particles entrained in a gas. The apparatus () includes an acoustic sensor () used to monitor the acoustic signals produced by collisions of pneumatically conveyed particles with the sensor (). Signal processing electronics and software () are used to determine, for each impact, the peak height of the acoustic signal. The particle size is calculated from the peak height distribution and either the signal (pulse) duration distribution or the airstream (impact) velocity, according to Hertzian Impact Theory.
