Top page Business Sensors Sensors To correspond stringent emission regulations, we offer a variety of sensor technology. Zirconia Oxygen Sensor This sensor is utilized for the air-fuel ratio control of the exhaust gas. Wide Range Oxygen Sensor By controlling in combination with a dedicated interface, it can control in accordance with the concentration of oxygen in the exhaust gas. NOx Sensor In order to respond to the recent strict NOx regulation, precise NOx detection has been requested. Temperature Sensor By monitoring the exhaust gas temperature, it is used in the optimal control of protection and exhaust gas after-treatment system of the exhaust system parts. We contribute to the improvement of clean and fuel efficiency of the exhaust gas. Knock Sensor A sensor that detects the knocking vibration of the engine with piezoelectric ceramics, used in spark advance control, will contribute to the improvement and fuel economy of the engine performance.
