DMR20-4/20S-G-C panel meter is a comprehensive 3 1/2 digit liquid crystal display panel meter. It has a microprocessor-based architecture with a digital display panel and a power decoupling and isolation function. With its high accuracy, stable performance, and low power consumption, it is suitable for a variety of applications in industrial control, power management, and automotive electronics.In industrial control, the panel meter can be used to measure and display the voltage, current and frequency values of a system . It can be used to display the status of a process, such as if it is running or stopped. It can also be used to measure electrical energy. In power management, the panel meter can be used to monitor and control the power supply of a system. It can be used to control the power supply voltage for the system, as well as to sense and display power overloads, overtemperature, and other fault conditions. In automotive electronics, the panel meter can be used to monitor important parameters of a vehicle, such as engine oil level, transmission gear ratio, and brake system performance.

Working Principles

The DMR20-4/20S-G-C panel meter is based on a microprocessor-based architecture. It consists of a digital display panel, a power decoupling and isolation function, and the power circuitry. The microprocessor is used to process and display the measured values. The digital display panel has a 3 1/2 digit LCD (liquid crystal display) screen that allows for easy display of readings. The power circuitry is used to decouple and isolate the measured signal from the system, ensuring a reliable measurement.The operation of the panel meter is simple. It connects to the power source via two wires. When power is supplied, current will flow through the meter and be accurately measured. This measured value is then processed by the microprocessor and displayed on the LCD screen. The power circuitry also ensures proper power supply and decoupling/isolation for the meter.In conclusion, the DMR20-4/20S-G-C panel meter is a reliable and comprehensive solution for a variety of industrial and automotive applications. With its high accuracy, stable performance, and low power consumption, it is an ideal choice for any application that requires precise measurements.
