This piezoelectric combustion pressure sensor can measure high-speed pressure fluctuations from a low temperature range of -40°C to a high temperature range of 350°C.
Based on the precision machining and assembly developed through the manufacture of watch components, the sensor is of high quality and high reliability, and can be installed in general-purpose vehicle engines.

In order to achieve carbon neutrality by 2050, not only electrification but also clean combustion using alternative fuels such as hydrogen and e-fuel is required.
