Sensors to supply Automotive Particle Bench (APB®) to Mahle


SEMTECH APBSALINE, MI, October 6, 2022 - Sensors, Inc. announces that it has entered into an agreement with Mahle GmbH to be its exclusive supplier of its Automotive Particle Bench (APB®) for the upcoming European Periodic Technical Inspection (PTI) programs scheduled to begin in 2022.

The measurement of opacity has been the standard for assessing the condition of diesel vehicles for over thirty years. As engine technology has advanced over the decades, it was clear that opacimeters were no longer capable of measuring particles from cleaner vehicles equipped with cleaner engines and advanced exhaust aftertreatment systems, and that a new measurement protocol was essential for a viable PTI program. After years of investigation and negotiation, authorities in the Netherlands, Germany and Belgium determined that a measure of particle number would satisfy the need to identify gross emitters. The European Commission is currently working on a recommendation for all Member States to introduce similar programs.

To meet this need, Sensors, Inc. embarked on a program to design, develop and manufacture a device that could accurately count particles as small as 23nm, under difficult environmental conditions. The company based the analyzer on the Condensation Particle Counter (CPC) technique, which has been employed for over a decade in their SEMTECH® Portable Emissions Measurement Systems (PEMS), and which is the similar to systems used for vehicle homologation.

MAHLE PMU 400Mahle, one of the largest manufacturers and distributors of equipment for PTI programs in Europe, chose Sensors, Inc. to provide its APB® measurement technology for integration into the Mahle PMU 400. This solution has been approved by the Dutch and Belgium authorities, and it was recently submitted to the German PTB for its homologation.

“We are proud to be chosen to supply Mahle with our APB® solution,” states Joe Morrill, CEO Sensors, Inc. “Mahle is a key supplier of equipment for the automotive aftermarket in Europe. Their demand for quality and performance was a critical factor in their selection of Sensors, Inc., as well as its proven capability to deliver thousands of analyzers that consistently meet those standards.”

Sensors, Inc. has over 50 years of experience in the design, development and manufacture of gas analysis and flow measurement technologies for a wide variety of demanding applications. Today, Sensors is a noted leader in the supply of gas analysis instrumentation and a leading manufacturer of innovative exhaust analysis solutions for automotive markets worldwide.
