Abstract
An airborne or liquid particle sensor with a number of advanced features is disclosed. The sensor includes an output channel generating an electrical signal for a particle passing through the sensor, where the electrical signal includes information related to the pulse. The information is processed by the sensor to determine a value that indicates a more accurate particle mass for a sample period than the average mass.
Claims18
A particle counting system comprising:
- at least one particle sensor including at least one output channel generating an electrical signal for a particle passing through the sensor,
- where the electrical signal for the output channel includes at least peak pulse height,
- where the peak pulse height of particle pulses processed by the sensor are summed in a value representing a total particle mass for the sensor, and
- where the value is used to indicate a more accurate particle mass for a sample period than the average mass calculated by multiplying the particle count by an average size for the channel.
