DESCRIPTION
The Honeywell HPM Series Particulate Matter Sensor is a
laser-based sensor which detects and counts particles using
light scattering. The detection concentration range is
0 µg/m3 to 1,000 µg/m3. A laser light source illuminates a
particle as it is pulled through the detection chamber. As
particles pass through the laser beam, the light reflects off
the particles and is recorded on the photo or light detector.
The light is then analyzed and converted to an electrical
signal to calculate particle concentration. The Honeywell
particle sensor provides information on the particle
concentration for given particle concentration range.
VALUE TO CUSTOMERS
• Enables the ability to more accurately and cost-
competitively monitor or control environmental particulate
• Industry-leading long life of 10 years of continuous use
• Proven EMC performance enables the ability to
perform more accurately in a variety of tough industrial
environments
• Faster response time of <6 s allows the HPM Series to
respond to environmental conditions in real time
• Enhanced reliability allows for use in harsh environments

Fan draws in air through inlet.
Air passes through the laser where the light reflected off the
particles is captured by the photodiode.
The photodiode passes information to the photoelectric converter
The photoelectric converter processes the signal from the particles into density
