What is a digital chart recorder?

Industrial digital chart recorders refers to an electronic instrument that remotely displays and counts signals such as pressure, temperature, flow, and liquid level in the industry.

Digital chart recorders record the collected data/calculated data in the internal storage system of the instrument with time as the base axis. It does not consume any commonly used recording facilities. For example: paper, pen and ink. Sino-Inst provides time-saving paperless chart recorders with up to 64 channels.

The stored data recorded in the instrument is displayed on the LCD screen after calculation and simulation. Commonly used LCD screens are widely used. On the LCD screen, digital display, bar graph display, curve display, alarm list, etc. can be displayed.

The data collected by the paperless recorder are commonly used: temperature, pressure, flow, liquid level, voltage, current, humidity, frequency, vibration, speed, etc.

Common Industrial Digital chart recorders:

Pressure recorder, flow recorder, speed recorder, temperature recorder, humidity recorder, liquid level recorder, level recorder, power recorder, F0 value recorder.

What are the functions of the Digital chart Recorder?

Paperless recorder is an instrument that can convert temperature and pressure into current, voltage, thermocouple, thermal resistance and other signals through a transmitter, and record and process the data.

Generally, it has functions such as alarm output, analog output, power distribution output, and communication.

The paperless recorder is an instrument that connects to a printer or U disk through RS485, RS232 communication, CF card transfer, and PC connection communication.

Digital chart recorder for pressure testing

The input signals of the paperless recorder are all “universal” full-switching signals, and can input standard analog signals 4~20MA, 1~5V, 0-20MA, 0~5V, 0~10V, etc. Generally, the output signal of the pressure transmitter is a passive signal of 4-20MA signal. As long as the recorder is equipped with a 24V power feed function, it can be displayed after setting the parameters according to the correct wiring indicated on the wiring diagram.
