Solar Powered Pump Drives: Solar Powered Pump Drives: Centrifugal and reciprocating. Their speed-torque characteristics are shown in Fig. 9.3. Centrifugal pump requires only a small torque to start whereas reciprocating…
Power Budget in Optical Fiber: The term Power Budget in Optical Fiber is the relationship between the power losses in fiber links and associated equipment and the available input power…
Bolometer: Bolometric measurements are based on the dissipation of RF power in a small temperature sensitive resistive element, called a Bolometer. This bolometer may be a short ultra thin wire…
Pyrometer Working Principle: When temperature being measured is very high and physical contact with the medium to be measured is impossible or impractical, optical pyrometer based on the principle of…
Q Meter: The overall efficiency of coils and capacitors intended for RF applications is best evaluated using the Q value. The Q Meter is used to measure some electrical properties…
Vector Impedance Meter (Direct Reading): If some knowledge of the reactive and resistive factors is needed, in addition to obtaining a direct reading of the magnitude of the impedance (Z),…
Working Principle of Digital Multimeter: Analog meters require no power supply, they give a better visual indication of changes and suffer less from electric noise and isolation problems. These meters…
Digital Voltmeters Features and Characteristics: Digital Voltmeters Features and Characteristics which includes measuring instruments that convert analog voltage signals into a digital or numeric readout. This digital readout can be displayed…
