Sensors Introduces New Particulate Mass Measurement System for In-Use Testing

SEMTECH PM2 Combines Real-Time Data with Cumulative Mass Measurements

SALINE, Mich. – September 26, 2017 – Sensors, Inc. today announced the launch of the SEMTECH PM2, an on-board vehicle emissions measurement system that combines real-time and cumulative particulate matter mass measurements. The system recently received approval from the U.S. Environmental Protection Agency (US EPA) for use as an alternative method for heavy duty in-use compliance testing applications, as put forth in the US EPA 40 CFR part 1065 requirements. (EPA's Notice of Alternate System Approval for SEMTECH PM2). By combining an ion mobility system with a gravimetric method, the system provides the benefits of both instantaneous data and accurate, time resolved mass measurement in a single, compact unit.

“The PM2 is the result of our excellent rapport with both worldwide regulatory agencies and our customer base,” stated Rob Wilson, Vice President, Marketing and Sales for Sensors, Inc. “It became clear that there was a need for both instantaneous data and cumulative measurements, along with a need for a system that is easy to install and operate. The PM2 achieves these goals, and further expands our SEMTECH line of on board emissions measurement systems.”

The on-board unit uses a single sample probe and heated line for both instantaneous and cumulative particulate mass measurements, thereby simplifying installation. The system measures particle sizes between 23 nanometers and 2.5 micrometers. The PM2 can be used as a stand-alone device, or can be combined with Sensors’ other SEMTECH products that measure gaseous pollutants.
