Paperless recorder working principle

A recorder is an instrument that converts the process of one or more variables over time or another variable into recognizable and readable signals. It can save the recorded signal changes for analysis and processing. The biggest feature of the recorder is that it can automatically record the slow change process and transient level change process of periodic or non-periodic multi-channel signals.

According to the types of input and output signals, recorders can be divided into analog-digital, digital-analog, analog-analog, digital-digital and other forms. Their main circuit varies according to the output form.

When the output is a digital signal, its main circuit is a memory circuit that can store digital information. It can send digital signals to tape drives, punchers or other equipment at any time. Or observe the analog waveform with an oscilloscope after proper conversion, such as digital memory and waveform memory.

When the output is an analog signal, the main circuit of the recorder is an analog amplifier drive circuit without storage function. The signal must be recorded on paper, photosensitive film, or tape immediately using appropriate recording devices and methods. The information can be saved for further analysis and processing. Such as various pen recorders, light recorders, plotters, tape recorders, etc.
