ETCR040A clamp current sensor is suitable for high-precision detection of AC current, high-order harmonic current, phase, electric energy, power, power factor and so on. Using new CT technology, portable, clamp design, no need to disconnect the tested line, non-contact measurement, safe and fast, can connect phase detection analyzer, industrial control device, data recorder, oscilloscope, harmonic analyzer, power quality analyzer, high-precision digital multimeter and so on. It is widely used in electric power, communications, meteorology, railway, oil field, construction, metrology, scientific research and teaching units, industrial and mining enterprises and other fields.

The iron core of ETCR040A clamp current sensor is made of iron-nickel alloy, and the influence of external magnetic field is minimal, which ensures high precision, high stability and high reliability of year-round uninterrupted measurement. The transformer can output current and voltage signals, and the measuring range, output signal and output interface of the transformer can be customized according to customer requirements.
