Introduction
Panel meters are essential components used in industrial applications. They are usually mounted on control panels with other instrumentation devices. Their purpose is to monitor, display, and control electrical parameters such as voltage, current, and power. In this article, we will examine the 7940018956 panel meter and its application field and working principle.
Application
The 7940018956 panel meter is primarily used in electronic measuring and controlling applications. It also features an auxiliary power supply, making it suitable for use with nuclear equipment and other sensitive equipment that require a highly accurate and reliable monitoring system. The panel meter is capable of monitoring, displaying, and controlling various electrical parameters, including temperature, humidity, amperage, voltage, and power. It is particularly useful in applications such as motor control, switching, process control, and high-voltage protection. Moreover, the meter is also suitable for applications such as lighting and security systems.
Working Principle
The 7940018956 panel meter operates on the basic power converter principle, which involves the conversion of electric energy from one form to another. It uses two or more transducers to measure the input power parameters. These transducers produce voltage and current signals, which are converted into electrical signals. The converted signals are then sent to a digital-to-analog converter. The analog signal is then fed into a digital display unit, which outputs the measured value. The panel meter can be used to accurately measure voltage, current, temperature, humidity, and power, and it is also capable of controlling these parameters. Additionally, the panel meter also features an alarm system that can be used to alert operators of potential problems.
Conclusion
The 7940018956 panel meter is an important component used in industrial applications. It is capable of monitoring, displaying, and controlling various electrical parameters, and it is suitable for use in motor control, switching, process control, and high-voltage protection. Furthermore, the panel meter also includes an auxiliary power supply and an alarm system. Thus, it is an important component for ensuring safety and accurate measurements in industrial applications.
