Recorders:

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 shown in Fig. 12.8. It …


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 a graphic recod of variations …


Digital Memory Waveform Recorder : The Digital Memory Waveform Recorder shown in Fig. 12.18, provides capability which is difficult to achieve by other methods. The block diagram (Fig. 12.18) is of a unit capable of recording four independent signals   …


Frequency Modulation Recording : When a more accurate response to dc voltages is required, an Frequency Modulation Recording system is generally used. In this FM system, the input signal is used to frequency modulate a carrier, i.e. the carrier signal …


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 field, as shown in Fig. …


Linear Motor Working Principle : Linear Motor Working Principle – The thermocouple or millivolt signal is amplified by a non-inverting MOSFET, chopper stabilised, feedback amplifier. This configuration has a very high input impedance and the current passing through the signal …


Magnetic Tape Recorder Working Principle : The major advantage of using a Magnetic Tape Recorder Working Principle is that once the data is recorded, it can be replayed an almost indefinite number of times. The recording period may vary from a …


Null Type Recorder Working Principle : 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 the measuring circuit, producing …


Strip Chart Recorder Application : The following are some of the thousands of Strip Chart Recorder Application for recorders in industry. 1.Temperature Recording A strip chart recorder may be used to provide a graphical record of temperature as a function of time. …


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 one of more variables …


XY Recorder Working : XY Recorder Working – In most research fields, it is often convenient to plot the instantaneous relationship between two variables , rather than to plot each variable separately as a function of time. In such …
