ACM20-4-AC1-G-F-C application field and working principle
Panel meters are often used to measure various electrical characteristics, such as voltage, current, power, and so on. The ACM20-4-AC1-G-F-C Panel Meter is a product in this category. This panel meter can measure AC power and is capable of measuring the frequency and current characteristics of that signal. In this article, we will discuss the application field and working principle of this panel meter.
Application Field
Generally speaking, ACM20-4-AC1-G-F-C Panel Meter is mainly used to measure the power and frequency of AC signals. It is widely used in industries such as power plants, factories, metallurgy, petrochemicals, and other places where the AC signals need to be monitored. In electrical and instrument control industry, this meter is usually used for monitoring the AC power of various electric devices and the power grid system. It can also be used to measure the power frequency, current and voltage characteristics of AC signals in an electric system.
Additionally, the ACM20-4-AC1-G-F-C Panel Meter can also be used for measuring ambient temperature, pressure and humidity, and can protect the machine from heat and humidity damage. It is quite convenient for users to get a real-time overview of the operating conditions of the equipment to ensure the normal and safe operation of the electric system.
Working Principle
The basic working principle of the ACM20-4-AC1-G-F-C Panel Meter is based on the Faraday’s law of electromagnetic induction. According to this law, an electric current through a conductor generates a magnetic field around it, and a changing magnetic flux can induce an electromotive force (EMF) in the conductor. This EMF can be used to measure the AC current in the circuit.
The ACM20-4-AC1-G-F-C Panel Meter utilizes this principle to measure the AC power. The AC signal is converted into an DC signal by a transformer, and the DC signal can be directly displayed on the digital display. This type of panel meter is also equipped with a filter capacitor that helps to filter out high-frequency noise. This panel meter also has an additional function of power failure display, which displays the power off statistics when the power supply is cut off.
In conclusion, the ACM20-4-AC1-G-F-C Panel Meter is an electrical pressure instrument designed to measure the power and frequency of AC signals. It is widely used in electric power, instrumentation control and other fields. The working principle of this device is based on Faraday\'s law of electromagnetic induction and it can provide accurate, reliable and low-cost measurement capabilities to users.
