Circular Chart Recorder Working Principle: Circular Chart Recorder Working Principle - As the name implies, the data is recorded on a flat circular chart. The basic assembly of a single pen circular chart recorder is…
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, it upsets the balance of…
Galvanometer Type Recorder: The D'Arsonval movement used in moving coil indicating instruments can also provide the movement in a Galvanometer Type Recorder. The D'Arsonval movement consists of a moving coil placed in a strong magnetic…
Strip Chart Recorder Working Principle: Strip Chart Recorder Working Principle are those in which data is recorded on a continuous roll of chart paper moving at a constant speed. The recorder records the variation of…
Definition of Recorder: Definition of Recorder - A recorder is a measuring instrument that displays a time-varying signal in a form easy to examine, even after the original signal has ceased to exist. Recorders generally provide…
Detectors Types: The Detectors Types are as follows For low frequency, the most convenient detector is the vibration galvanometer. For ordinary laboratory work at frequencies up to a few 100 Hz, the moving coil type of…
Wagner Ground Connection: Wagner Ground Connection - When performing measurements at high frequency, stray capacitances between the various bridge elements and ground, and between the bridge arms themselves, become significant. This introduces an error in…
Wien Bridge Circuit Diagram: The Wien Bridge Circuit Diagram shown in Fig. 11.27 has a series RC combination in one arm and a parallel combination in the adjoining arm. Wien's bridge in its basic form,…
Measurement of Capacitance using Schering Bridge: A very important bridge used for the precision measurement of capacitors and their insulating properties is the Schering Bridge Experiment. Schering Bridge basic circuit arrangement is given in Fig.…
Hays Bridge Circuit: Hays Bridge Circuit, shown in Fig. 11.23, differs from Maxwell's bridge by having a resistance R1 in series with a standard capacitor C1 instead of a parallel. For large phase angles, R1 needs…
