CTS acquires Filter Sensing Technologies

5 November 2015

CTS Corporation announced that it has acquired Filter Sensing Technologies (FST). FST is a developer of radio frequency (RF)-based sensors for monitoring of soot levels on diesel particulate filters (DPF) in passenger cars, commercial vehicles, off-road vehicles and other transportation applications. The acquisition also provides CTS with intellectual property in this field. The financial terms were not disclosed.

FST is a start-up founded in 2008 by two Massachusetts Institute of Technology (MIT) Ph.D. graduates—Alexander Sappok and Leslie Bromberg who, combined, hold over 50 patents related to energy efficiency and emissions reduction technologies. FST is located in the Boston, MA area.

The acquisition of FST provides CTS a sensing technology utilizing radio/microwave frequencies to directly measure particulate levels in vehicle filters. Compared to existing sensors, the RF direct measurement method can improve the control and diagnostics of aftertreatment systems and enable fuel economy improvements due to better control of DPF regeneration.

CTS, based in Elkhart, IN, is a manufacturer of sensors, actuators and electronic components to OEMs in the aerospace, communications, defense, industrial, information technology, medical, and transportation markets.
