Panel Meters

Panel meters are devices used for measuring and displaying electrical signals. They are one of the major categories of instrumentation and are used for both industrial and consumer applications. DCA5-20PC-7-DC4-RL-C is one such panel meter; it is widely used in both industrial and consumer applications.

Application Field and Working Principle

DCA5-20PC-7-DC4-RL-C panel meter is suitable for voltage, current, frequency, power and phase measurement in electric network, and is applicable for most single-phase and polyphase power systems. It utilizes the vertical magnetic interaction principle, which is mostly used for measuring current. It also has a compact design with self-mounted ultra-thin structure, and is equipped with a white light LED display screen that can show clearly the measure values from various angles. It also has built-in functions such as data logging and alarm functions, making this panel meter suitable for different kinds of monitoring and automatic control purposes.

For voltage measurement, the DCA5-20PC-7-DC4-RL-C panel meter has a built-in differential transformer that measures AC voltage. The magnetic flux generated through the transformer core causes the iron core to rotate accordingly. The rotation of the core is then converted into an electrical signal and displayed on the LED screen. For current measurement, the panel meter has a built-in current transformer that measures AC current. The magnetic flux generated through the transformer core causes the iron core to rotate accordingly. The rotation of the core is then converted into an electrical signal and displayed on the LED screen.

The DCA5-20PC-7-DC4-RL-C panel meter can also be used for power measurement. It has a built-in electronic transducer which is connected to both current and voltage measuring circuits. The transducer converts the signals from the current and voltage measuring circuits into an electrical signal, which is displayed on the LED screen. The panel meter is also able to measure frequency as it has a frequency measuring circuit, which can detect the frequency of the AC voltage or current inputs. The detected frequency is then displayed on the LED screen.

For phase measurement, the DCA5-20PC-7-DC4-RL-C panel meter has a phase-shift detector circuit. This circuit is used to measure the differences in phase between the voltage and current inputs. The phase differences are then displayed on the LED screen. Apart from phase measurement, this panel meter can also measure power factor. This is achieved by measuring the phase angle between the voltage and current inputs and calculating the power factor using the measured phase angle.

Overall, DCA5-20PC-7-DC4-RL-C panel meter is a reliable and accurate instrument for measuring several electrical signals, such as voltage, current, frequency, power and phase. It has a compact design, white-light LED display and built-in functions, which makes it an ideal choice for most industrial and consumer applications.
