Magnetic Flow Meters: Magnetic Flow Meters are the first type of flowmeters to be considered for high corrosive applications and for applications involving measurement of erosive slurries. These meters work…
Flow Measurement (Mechanical Transducers): The measurement of flow rate and quantity is the oldest of all measurements of process variables in the field of instrumentation. It is used to determine…
Automatic Bridge Circuit: The bridges discussed so far require that the controls be adjusted for balance after each capacitor (or other devices being tested) is connected to the bridge. In…
Algorithm for Short Circuit Computation: So far we have carried out short circuit calculations for simple systems whose passive networks can be easily reduced. In this section we extend our…
Short Circuit Current Computation through Thevenin Theorem: An alternate method of computing Short Circuit Current Computation is through the application of the Thevenin theorem. This Short Circuit Current Computation method…
Types of Forced Commutation: It was observed from the discussion on choppers and inverters that in thyristor systems fed from dc supply, the forward current does not pass through zero…
Foldback Current Limiting Circuit: The disadvantage of constant current limit is relatively large power dissipation in the series pass transistor when the load terminals are shorted. Thus a large power…
Constant Current Limiting Circuit: A block of series regulation using simple Constant Current Limiting Circuit is shown in the Fig. 2.119. It is also called short circuit protection circuit as…
