Mass moment of inertia for a particle: The mass moment of inertia is one measure of the distribution of the mass of an object relative to a given axis. where O-O is the axis around which one is evaluating the mass moment of inertia, and r is the perpendicular distance between the mass and the axis O-O.
Differential Pressure DP Sensor The differential pressure sensor is used for flowmeasurement of the Diesel Particulate Filter (DPF). Thissensor has two pressure ports and senses the differencein pressure between the two ports.
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level. The interposed buffer amplifier prevents the second circuit from loading the first circuit unacceptably and interfering with its desired operation.
