Thermistor Working Principle: Thermistor Working Principle - The electrical resistance of most materials changes with temperature. By selecting materials that are very temperature sensitive, devices that are useful in temperature…
Types of Strain Gauge Transducer: Types of Strain Gauge Transducer are three types, namely Wire Strain Gauge Foil Strain Gauge Semiconductor Strain Gauge Wire Strain Gauge: Wire Strain Gauge has…
Null Type Recorder: These Null Type Recorder Working Principle of self-balancing or null conditions. When an input is given to the measuring circuit of the recorder from a sensor or transducer,…
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),…
Output Power Meter Working Principle: The Output Power Meter Working Principle is designed to directly measure the output power in an arbitrary load. The instrument provides a set of resistive…
Spectrum Analyzer Block Diagram: Spectrum Analyzer Block Diagram - The most common way of observing signals is to display them on an oscilloscope, with time as the X-axis (i.e. amplitude…
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…
