INTRODUCTION
| MEWOI168A High Accuracy Clamp leakage current sensor for AC leakage current, current, high harmonic current, phase, power, power factor and other detection. Range: 0.0A~2000A, jaw size is Φ68mm. The sensor adopts the clamp-shaped structure, which can be measured without disconnecting the measured circuit. The permalloy iron core and double-layer shielding technology are used to ensure the accuracy and stability of the measurement. Non-contact measurement methods are adopted, and the operation is safe and simple. It can be connected to phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, and high-precision digital multimeters. |
