TOP > Combustion Pressure Sensor

These are piezoelectric in-cylinder pressure sensors capable of measuring high-speed pressure changes from the low-temperature range at -40℃ to the high-temperature range at 350℃. Based on the precision machining and precision assembly technology that we built up while manufacturing watch components, we have succeeded in installing these sensors in general vehicle engines with high quality and high reliability.
To achieve carbon neutrality in 2050, there is demand for clean combustion using alternative fuels such as hydrogen and e-fuels in tandem with the transition to electric power, and we are taking all internal combustion engines to the development and advancement with CPS products that have a track record of installation in mass-produced vehicles.
