Fuel Gauging

Optical fuel gauging system is an optical sensor measuring level of fluid system. This system uses optical refraction. In air, light coming out from illuminators goes back to receiver because of complete reflection of prism. In liquid, the light passes the prism and does not reach to receiver. Photocells including illuminator, receiver and prism are put vertically to generate signal depending on liquid level.


GPS/AHRS is TAMAGAWA SEIKI's new Attitude and Heading Reference System. MEMS gyroscope and MEMS accelerometer make it highly reliable, lightweight and compact. In addition, since it is equipped with a GPS receiver, you can use the GPS data as an aiding Source by simply connecting a GPS antenna. The algorithm uses the Kalman filters and combines the data from gyroscopes and accelerometers with GPS data to enhance attitude accuracy. This equipment is in the development phase and equipment certification activities.
