Flux gate detection

Flux gate detection delivers outstanding linear properties, and can measure currents of a wide range of magnitudes with high accuracy.

The fluxgate components used for DC detection have very low offset over a wide temperature range due to their operating principle, resulting in high accuracy and excellent temperature stability. It is ideal for measurements that require high accuracy, such as Power analyzers and Power meters. It can be used for measurement such as inverter efficiency, inverter output power, reactor/transformer loss, and long-term DC measurements.

Automatic Phase Correction function

To accurately measure high frequency and low power factor, it is important to correct phase errors. The PW8001 automatically acquires and corrects the phase of the current sensor with 0.001°resolution, bringing out the best performance of the current sensor without any effort.

Automatic current sensor detection by Power Analyzer PW8001

The current sensor is equipped with a memory (I2C-EEPROM).

When the current sensor is connected to the Power Analyzer PW8001, the phase correction data, rated current, sensor's model name, and serial number are automatically recognized by the instrument.

In the past, phase correction values had to be entered manually.

However, thanks to the automatic detection system of current sensor information, forgetting settings and typing errors are eliminated, allowing for more accurate power calculations.
