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 …

Potentiometric Recorder Working Principle (Multipoint)

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 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

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 …

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. …

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 …
