Walker Products releases exhaust sensors for U.S., European diesel markets
Walker’s coverage of exhaust temperature sensors (ETS) for U.S. diesel applications includes 53 part numbers covering diesel vehicles from 2006 – 2014 for Chevrolet, GMC, Jeep, Mercedes Benz, Audi and Volkswagen applications.
European coverage includes 233 part numbers covering diesel vehicles from 2004 – 2014 for Alfa Romeo, Audi, Fiat, Lancia, Mercedes, Opel, Saab, Seat, Skoda Volkswagen and Volvo.
An ETS/HTS typically measures temperatures up to 900 degrees C in the exhaust system of the vehicle. The sensing element of an ETS/HTS changes in resistance with changes in temperature. The engine computer measures the resistance and calculates the temperature.
Depending on the location of the ETS/HTS, the engine computer uses the temperature information to control a wide variety of processes in the vehicle. These processes include particulate filter regeneration, selective catalytic reduction (SCR), exhaust gas recirculation, turbo boost, and overall engine combustion.
The Walker ETS/HTS utilizes an OE construction consisting of high temperature metals and ceramics. Walker said this allows its sensors to deliver stable and accurate output despite the heat, vibration and contamination found in the exhaust system.
Most ETS/HTS are used to monitor the particulate filter. In these cases, failure to replace a defective ETS/HTS will result in an obstructed filter and possible engine damage.
Walker Products began supplying the fuel system needs of the automotive industry in 1946. Today, Walker is one of the largest privately owned manufacturers of fuel system components and engine management devices. The company serves major OEMs, co-manufacturers, rebuilders and retail customers in the fuel, engine management and exhaust markets worldwide.
