How are True RMS Voltage Transducers Classified Based on the Number of Channels?
The number of channels of a true RMS voltage transducer significantly affects its ability to accurately measure the RMS voltage of a signal. The more channels a true RMS transducer has, the more it can capture a wider range of signal waveforms, and the more it can fully analyze the changes in the signal over time, which may result in more accurate RMS calculation results.
The following is an introduction to the classification of true RMS voltage transducers based on the number of channels and their application scenarios.
Single-channel (single-phase) true RMS voltage transducer
A single-channel true RMS voltage transducer measures the voltage on only one input line, one voltage waveform at a time. It is low-cost due to its simple, compact design, is very easy to install, and is highly compatible.
It is mainly used in single-phase AC systems, HVAC systems, and battery management systems. The CR4520 supplied by OFweek is a high-precision single-phase true RMS AC voltage transducer.
Dual-channel true RMS voltage transducer
It can measure the voltage of two independent inputs simultaneously or alternately. It is mostly used to detect systems with two independent single-phase lines. It is very suitable for comparing two voltage sources and helps to compare and analyze voltage signals.
Three-channel (three-phase) true RMS voltage transducer
It can measure the voltage on three lines at the same time and is often used in three-phase AC systems. The design of a three-phase true RMS voltage transducer is relatively more complex and more expensive. Careful installation is required to ensure accurate phase alignment.
Three-phase true RMS voltage sensor is mostly used to detect high-power complex power systems, such as industrial power systems, motor control, and monitoring, etc.
Multi-channel (4+ channel) true RMS voltage transducer
Multi-channel true RMS voltage sensor has multiple input channels and can measure more than three RMS voltages at the same time. It has the advantages of high multi-point monitoring efficiency and can be integrated with data logging or communication functions. It is widely used in data centers, multi-line industrial panels, power distribution units, and advanced diagnostics in complex systems.
In summary, the cost and installation complexity of a true RMS voltage sensor will increase with the increase in the number of channels. When choosing, the needs of the detection application scenario should be fully considered.
