Tips: What is a True RMS Current Sensor?
A True RMS Current Sensor is a device used to measure the root mean square (RMS) value of an electrical current, providing accurate readings regardless of the waveform shape. Unlike traditional sensors that may only accurately measure sinusoidal AC currents, a True RMS sensor can measure both AC and DC currents, including non-sinusoidal waveforms such as those found in modern electronic devices and industrial machinery. By calculating the RMS value, which represents the effective value of the current, this sensor offers precise measurements that reflect the real power consumption or load, making it ideal for applications where the current waveform is irregular or fluctuating.
