Panel Meters

A Panel Meter is a device used in industry or home applications to measure or display various types of information, such as voltage, current, temperature or frequency. DK857A is one of commonly used Panel Meter in the market for its wide application field and easy-to-understand working principle.

Application Field of DK857A

DK857A Panel Meter is designed for mV Range, A&V Range, Signal Conditioning, Data Acquisition, Data Monitoring, Waveform Recording, etc. Professionals can always find a way to make the best use of DK857A to perform various operations including but not limited to battery testing, motor control, automated process monitoring, air pressure monitoring, temperature control, and many other industrial applications.

Working Principle of DK857A

DK857A panel meter mainly consists of a function generator, signal conditioning, and digital display. The function generator produces a signal input that is received by the signal conditioning circuit which then amplifies and filters the signal. After that, the signal is relayed to the digital display to display the signal in numerical form or graphical form. In order to show accurate information, this data needs to be calibrated. The calibrated data can be input from the computer or machine to the meter, and can also be measured in real time.

Apart from that, DK857A is built with an additional feature known as Trigger Input. This feature allows DK857A to act as a controller to monitor any specific variable or event. The trigger input then sends a signal to the meter to process the data depending on the user’s preference. The user can decide the data to be stored in the memory or to be displayed.

Advantages of DK857A

The primary advantages of DK857A are its relatively small physical size, easy installation, user-friendly operation, and wide application field. Being a digital instrument, it requires only little maintenance. It has low environmental impact and is very reliable when compared to older analog instruments. It can also be used as an alarm or process controller. It is designed for both indoor and outdoor applications with a wide range of operating temperatures.

Conclusion

DK857A is an ideal analog instrument for industrial and home applications due to its wide application field and easy-to-understand working principle. It is particularly suitable for use in process monitoring, temperature monitoring, battery testing, motor control, air pressure monitoring, and waveform recording. With the right calibration and settings, it can deliver accurate information with low environmental impact and minimal maintenance requirement.
