Strip Chart Recorder Application

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. There are two primary methods used for recording temperature, the thermocouple method and the […]

Digital Memory Waveform Recorder

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    simultaneously. The practical implementation of this concept rests on the ready availability, small size and reasonable […]

Linear Motor Working Principle

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 source is a maximum of 0.5 nA (without broken sensor protection). With the use of span […]

Frequency Modulation Recording

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 is frequency modulated by the input signal (FM modula­tion), which is then recorded on the tape […]

Magnetic Tape Recorder Working Principle

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 few minutes to several days. Speed translation of the data captured can be provided, i.e. […]

XY Recorder Working

XY Recorder Working: XY Recorder Working – In most research fields, it is often convenient to plot the instantaneous relationship between two variables [Y = f(x)], rather than to plot each variable separately as a function of time. In such cases, the X—Y recorder is used, in which one variable is plotted against another variable. […]

Circular Chart Recorder Working Principle

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 consists of a measuring element, an operating mechanism, a chart drive, and a recording device, […]

Null Type Recorder Working Principle

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 the measuring circuit, producing an error voltage which operates some other device, which in turn restores the balance or brings […]

Galvanometer Type Recorder

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. 12.2(a). In a galvanometer type recorder, the pointer of the D’Arsonval movement is fitted with […]

Strip Chart Recorder Working Principle

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 with respect to time. The basic element of a Strip Chart Recorder Working Principle consists of […]
