Combustion pressure sensor (cylinder pressure sensor)

Measuring the future of internal combustion engines, Citizen-quality combustion pressure (cylinder pressure) sensor.

Our combustion pressure sensor (cylinder pressure sensor) is a sensor developed to measure pressure fluctuations occurring inside the cylinders of internal combustion engines in real-time and with high precision. Main Features: High Response Speed: It has a high response speed that can accurately track changes even in phenomena that fluctuate greatly in a short time, such as combustion. High Durability and Long Lifespan: Through precision processing and assembly techniques cultivated in watch component manufacturing, along with strict quality control, it achieves high durability capable of withstanding the harsh environments unique to engines, such as vibrations, thermal shocks, and pressure fluctuations. The company conducts durability tests to verify performance in the gigacycle order.

The area where Citizen Fine Devices demonstrates its strength is in the realm of functional components that require small size, precision, high accuracy, and high detail. We believe that our mission is to continue providing high-value-added microdevice products by leveraging the unique technologies we have developed over many years. Utilizing metal processing technology rooted in watch manufacturing, we have consistently supplied small, high-precision components to our customers for many years through a fully integrated production line that encompasses process design, machining, assembly, and functional testing, along with the unique development of our own processing machines. Additionally, mass-producing components with high precision and efficiency using brittle materials is also one of our core technologies. By integrating material technology with ultra-precision machining, thin-film technology, and bonding technology, we produce not only high-precision components such as ceramics and quartz but also high-quality functional device products like liquid crystal devices and sensing devices. Continuing to provide high-value-added products to the market is a significant dream for our employees. We will contribute to the creation of new value through manufacturing driven by the challenge spirit of each individual, working towards the realization of that dream.
