Particulate Analyzer provides real time measurements.
Press Release Summary:
For stationary or portable use, PM-300 particulate analyzer enables real-time measurement of particle sizes emitted by internal combustion engines in 100 nm increments down to 300 nm. Exhaust is drawn through analyzer via heated sample line and temperature controlled dilution system with mass flow controllers. Mini-diluter mixing chamber combines raw exhaust fraction with clean air. Analyzer generates curves with data-sampling rate of 1 sec. Original Press Release:
Design Development of Sensors, Inc., PM-300, Provides Real-Time Diesel, Gasoline Emissions Particulate Analysis
SALINE, Mich., January 14 -- Sensors, Inc., has introduced a significant advancement in the analysis of particulates in diesel and gasoline engines, the PM-300.
"Particulates are a very 'hot' topic today in our understanding of engine emissions and how they affect our health," says Sensors, Inc., president Andrew Reading, PhD. "Up until now there have been several particulate size measurement techniques available, capable of generating size-distribution
measurement. But most have been laboratory-type instruments with slow response time that could only do stationary tests."
The PM-300 device enables real-time measurement of the size of particles emitted by internal combustion engines in 100nm increments down to 300nm. Exhaust is drawn through the analyzer through a heated sample line (controlled at 195 degrees C to preserve sample integrity) and a temperature controlled
multi-stage "mini" dilution system equipped with high precision mass flow controllers. The mini-diluter is a mixing chamber that allows the raw exhaust fraction to be combined with a predetermined amount of clean air prior to measurement.
The analyzer generates a family of curves, each representing a specific particle size over the full operating range of the instrument. The data-sampling rate of the unit is 1 second, enabling accurate resolution of transient events.
The PM-300 is designed for stationary (laboratory and test cell
environments), portable (on a mobile cart for relocation from test cell to test cell) and in-use, on-road applications (for real time emissions testing). In-use, the instrument can be located in the trunk area or cargo bed (truck or van) along with
a deep cycle battery. The heated line is routed to the tailpipe where a standard Sensors, Inc., probe is inserted.
Sensors, Inc., has been a leader over the past 30 years in the design and manufacture of OEM gas analyzers for the inspection and maintenance (I/M) industry. In the past four years the company has shifted its R&D focus to on-road, in-use technology, made possible by Sensors, Inc.'s development of robust, solid-state analytical techniques. PM-300 is one of several such products the company now offers.
