Because the slow sensor is made of nothing but titanium, platinum, silver and glass, its special membrane can be cleaned by a high power ultrasonic micro beam concentrated onto the 2mm sensing area on the tip. The fast second O 2 sensor is equipped with a propulsion micro device and a new proprietary long term cleaning system. Microturbulence is recorded down to 0.02 cm per second with a new, proprietary strategy an head.
All data is multiplexed by the ultra low power processing unit.
Simultaneously the batteries recharge. The 62 mm diameter titanium housing is 4000 m certified. Fig 2 and 3. In these heads a dye changes color and intensity after blue light flashing with declining oxygen tensions, a setup known for decades. As soon as they become available in reliable, stable, fast and rugged versions they will be incorporated in the ecoSCAN system as additional subsystems for adding higher spatial resolutions.
