DK757B Industrial Controls

DK757B application field and working principle

DK757B is a kind of digital panel meter that can be used in a variety of fields and applications. It can measure DC voltage, AC voltage, DC current, AC current, temperature, resistance, frequency, phase angle, power factor, etc. In addition, DK757B also has functions such as voltage gain, current gain, voltage output, current output.

The working principle of DK757B is as follows: firstly, DK757B can sense the voltage, current, or temperature signals from the application, and then convert them into digital signals and send them to the A/D converter on the main chip. After A/D conversion, the microprocessor will process the data and display it on the LCD screen according to the parameters set by the control keys.

DK757B can be applied primarily in the following three areas: Monitoring, Control and Automation. In the monitoring applications, the panel meter is used to display the variety of signals measured by the application for easy visual inspection. It is very convenient for people to observe the performance of the system. In the control applications, DK757B is used to control the setting, operation or indication of electrical parameters, thus achieving the purpose of automatic control. In the automation applications, DK757B can be used to collect and store the status of the system automatically in order to realize the purpose of automation.

In conclusion, DK757B is a very versatile digital panel meter that can be used in a variety of fields and applications. Its functions such as voltage gain, current gain, voltage output, and current output make it a very important device in monitoring, control and automation applications.
