Reed Switches in Exhaust Emissions Sensing

Automotive exhaust fume emission

Pollution, greenhouse gases and smog play a large role in global warming and it is most important to ensure that automobile emissions are monitored. These polluting gases which make up most of emission levels in automobiles are reduced by catalytic converters which convert them into less harmful gases. A simple vane with a magnet fitted inside the tailpipe of automobiles is used to trigger a reed switch which provides feedback to the CPU is used to adjust fuel mix ratio thereby reducing emission levels. Miniature molded reed switches such as the R3 or the R5 or our MS-225 or MS-228 threaded sensors are suitable for such applications where dirt, grime, and moisture can be expected.
