Panel meters are a type of measuring instrument commonly used for electric meters. A panel meter is a device, typically equipped with one or more analog or digital displays or LEDs, that is used to indicate a set of data values or readings. Panel meters are often used to monitor current, voltage, power, frequency, and other electrical metrics in an electric circuit.

The R3PB-FRQ-50/120-10-U is a panel meter specifically designed to measure the frequency of a given electrical circuit. It can measure AC or DC signals across a wide range of frequencies, from as low as 50 Hz to as high as 120 kHz. This type of panel meter is commonly used in frequent-switching motor drives, as well as in other industrial applications.

The principle of operation of the R3PB-FRQ-50/120-10-U panel meter is based on sampling. A current transformer (CT) is connected to the incoming power line, which produces an output voltage that is proportional to the current flowing through the line. This output voltage is then sampled at regular intervals by the analog-to-digital converter (ADC) of the panel meter and converted into a digital value, which is then used to calculate the frequency of the circuit.

In addition, the R3PB-FRQ-50/120-10-U panel meter offers a number of features that are designed to improve the accuracy and reliability of the readings. For example, the device is equipped with a temperature-compensated reference that provides greater accuracy over a wide range of temperatures. Additionally, the device includes an EMI filter to reduce interference from other sources. Furthermore, the unit includes a built-in power supply that eliminates the need for an external power source.

The R3PB-FRQ-50/120-10-U panel meter is specifically designed for industrial applications where accuracy and reliability are important. It can be used to measure AC and DC signals across a wide range of frequencies and offers features that are designed to improve accuracy and reliability. This type of panel meter is ideal for frequent-switching motor drives and other industrial applications.
