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 …
Digital Memory Waveform Recorder (DWR): The Digital Memory Waveform Recorder (DWR) 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 …
Potentiometric Recorder Working Principle (Multipoint): Potentiometric Recorder Working Principle – The thermocouple or millivolt signal is amplified by a non-inverting MOSFET, chopper stabilized, 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 …

Digital Data Recording System: Digital Data Recording – Digital magnetic tapes are often used as storage devices in digital data processing applications. Digital tape units are of two types, incremental and synchronous. Incremental digital recorders are commanded to step ahead (increment) for each digital character to be recorded. Input data may be at a relatively …
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: 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 – 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 – 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: 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: 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 …
