The recorder is a new type of intelligent system paperless recording instrument based on CPU, scale integrated circuit, large space flash storage, signal intelligent regulation, smartbus system bus and mass flowmeter. It adopts 160 × 128 solid-color LCD with long service life LED power panel, which is suitable for 4 / 8 / 16 channel analog input universal input or 2 /4 / 8 channel analog output and 12 channel alarm output, setting data information and recording data information have the function of power-off maintenance, with small size, large number of channels, low power, high precision, strong practicability, stable operation and credibility characteristics of colleges and universities.

Basic concept of recorder

It can store the recorded signal transformation for analysis and solution. The recorder acid-base resistant flowmeter is an instrument which transforms one or several independent variables into distinguishable and readable signals at any time, anywhere or in the whole process of another independent variable transformation.

The key performance indexes of the recorder are output power, dynamic range of input signal, recording linearity, discrimination, harmonic distortion, response speed, paper feeding degree and stability. There must be complicated circuit and organization for the tape drive as the external equipment of electronic computer. The Zui characteristic of recorder heavy oil flowmeter is that it can automatically record the whole process of slow transition and transient level transition of regular or aperiodic multichannel signals. According to the types of output signals, recorders can be divided into analog-to-digital, digital to analog, analog to analog, digital to digital and other ways. Their main circuits are different according to different output ways. When the output is a large digital signal, the key circuit is a memory circuit that can store electronic information. It can give the large digital signal to tape drive, punch or other machine equipment at any time and anywhere, or use a digital oscilloscope to observe and simulate the analog wave type, such as large digital memory and wave type memory after appropriate conversion. When the output is analog signal, the main circuit of recorder behavior is the circuit of analog variable size driver without storage function. It is necessary to use appropriate recording equipment and mode immediately The information can be saved only when the signal is recorded on paper, light sensitive film or recording tape, which is conducive to further analysis and solution, such as various inquiry recorders, light source recorders, plotters, recording tape recorders, etc. There are two key types of digital and analog circuits, i.e. the immediately enlarged driver type, such as the interrogator recorder and the fully automatic equalization type, such as the plotter or the X-Y recorder
