Airflow was measured by fast response time airflow sensors (bidirectional micro bridge mass airflow sensor, AWM 2000 series, Honeywell®).
The whole system was based on a proportional-integral-derivative (PID) controller composed of an electronic card, a miniature proportional valve (VSO® model, Parker Precision Fluidics) and an air flow sensor (micro bridge mass airflow sensor, AWM 40000 series, Honeywell®).
In mid-March, when deliveries of mass airflow sensors from Hitachi became uncertain, G.M. shut a plant in Shreveport, La .— the first auto plant in North America to close as a result of the disaster — that makes slow-selling, small pickup trucks, and redistributed the 2,200 sensors on hand in Shreveport to plants building higher-margin vehicles.
Typical sensors include the following: mass airflow, exhaust oxygen, engine revolutions per minute, manifold absolute pressure, barometric pressure, coolant temperature, throttle position, knock, vehicle speed, air-conditioning load, power steering load, crankshaft position, and camshaft position.
I had chest and stomach belts for breathing, an airflow sensor in my nostrils, an oxygen saturation monitor on my finger and a "snore mike" taped to my neck.
Tadashi Hisanaga, a Hitachi Group spokesman, said the company expected the two plants that make the airflow sensor to be "up and running by Friday or Saturday".
The robot has bilateral chemical sensors, an airflow sensor and tactile whiskers to detect obstacles.
The body mass, airflow obstruction, dyspnoea and exercise capacity index (BODE index) for COPD was calculated accordingly [20].
The theoretical model of an MMPF airflow sensor has been established.
After successful polarization, the cantilevered MMPF could be used as an airflow sensor.
Consequently, the accuracy of the VAV airflow sensor is highly important to the VAV system operation, and an inaccuracy of the VAV airflow sensor could lead to an energy waste or insufficient ventilation.
