Variable Resistance Transducer
INTRODUCTION Electrical circuits consist of combinations of the three passive elements: resistor, inductor and capacitor. The primary parameters that describe them are respectively resistance, self or mutual inductance and capacitance.…
HUMIDITY MEASUREMENT USING RESISTIVE TRANSDUCERS
Humidity Humidity is the measure of water vapour present in a gas. It is usually measured as absolute humidity, relative humidity or dew point temperature. Absolute humidity or Specific humidity…
CALIBRATION
Calibration is an essential process to be undertaken for each instrument and measuring system frequently. A reference standard atleast ten times more accurate than the instrument under test is normally…
Class B Power Amplifier
When the collector current flows only during the positive half cycle of the input signal, the power amplifier is known as class B power amplifier. Class B Operation The biasing of…
DIGITAL VOLTMETERS
The digital voltmeter (DVM) displays measurements of dc or ac voltages as discrete numerals instead of a pointer deflection on a continuous scale as in analog devices. Numerical readout is…
Lithographic Processes
The process of lithographically fabricating microcomponents is analogous to printing a photograph in a darkroom. In phorography, an energy sensitive material (photo emulsion) is placed as a thin coating on…
Optical fibre
In all developed countries, long-distance communication links (which used to be called 'trunks', by analogy to 'trunk road') nearly always use optical fibre. It is only where the terrain makes…
Different measurements of Capacitive Transducers
• Capacitive Level Transducer • Capacitive Displacement Transducer • Capacitive Thickness Transducer • Capacitive Strain Transducer • Capacitive Pressure Transducer • Capacitive Proximity Transducer • Capacitive Moisture Transducer • Capacitive Hygrometer • Capacitive Microphone Capacitive Level Transducer (Variation of Dielectric…
Digital Tachometer Circuit Operation using Microcontroller and their Types
A digital tachometer is a digital device that measures and indicates the speed of a rotating object. A rotating object may be a bike tire, a car tire or a…
