The bellows, diaphragm, and Bourdon tube pressure sensors all exhibit second order time response. This means that a sudden change in pressure will cause an oscillation in the displacement and, therefore in the sensor output. Because they are like springs, they have an effective spring constant and mass, so the frequency can be estimated by f=(1/2*pi)(squk/m). Consider a bellows with an effective spring constant of 3500 N/m and a mass of 50 g. The effective area against which the pressure acts is 0.5in2. Calculate:
a. The bellows deflection for a pressure of 20 psi andb. The natural frequency of oscillation.
very useful not only in obtaining the rectangular and polar forms of complex numbers
Suppose that the sequence 110010011 is used as a synchronization sequence preamble to a data packet. Propose a method that can be used to allow the channel to distinguish the synchronization sequence from an identical data sequence within the pack..
A system is needed to measure flow, which continuously cycles between 20 and 30 gal/min with a period of 30 sec. The required output is a voltage varying from -2.5 to +2.5 V for the cycling flow range. The sensor to be used has a transfer function..
