DK721 Industrial Controls

DK721 Application Fields and Working Principles

Introduction

The DK721 system is a dynamic pressure digital display instrument, which can measure liquid, gas, steam or hydraulic pressure in a two-way connection. It has a solid, reliable and beautiful structure, and its shape is exquisite and small. It has the characteristics of long service life, anti-humidity and anti-vibration. It is suitable for partial or full-scale digital display in the production process. It can also be used as a digital display switch or alarm.

Application Fields

The DK721 is suitable for a variety of industries, including engineering machinery, electric power, light industry, metallurgy, gas, oil, chemical industry, urban construction and other industries. It can be widely applied to various pressure transmitters of liquid, gas, steam and hydraulic pressure range.

Working Principles

The DK721 system uses the principle of electric bridge to convert the pressure signal from the pressure transmitter into a field indicating the pressure value. This pressure signal is converted into a voltage or frequency signal on the transmitted line, and then it is input to the electric circuit. After being converted by the amplifier, the signal is filtered, then processed by a special microprocessor (special chip) and displayed by digital or analog devices.

Moreover, the DK721 has a special algorithm that can adjust the input signal according to the required pressure range, and display the digital pressure value directly, just like the ordinary electronic digital display instrument. In addition, the DK721 can also achieve the alarm output function, when the pressure exceeds the set pressure range, the alarm will be issued.

Conclusion

In conclusion, the DK721 digital display instrument is a multifunctional electric pressure display instrument. Its application field is wide, which is suitable for various pressure transmitters. Its working principle is based on the electric bridge theory, converting the signal to digital or analog, so as to provide data for industrial enterprises.
