ETCR030D Clamp DC Leakage Current Sensor, suitable for high-precision DC leakage current, DC current on-line detection, range: DC 0.1mA ~ 100mA, jaw size 25mm x 30mm. The sensor adopts the clamp-shaped CT structure, which can be measured without disconnecting the measured circuit. Permalloy iron core and double-layer shielding technology are adopted, and the anti-interference ability is strong, ensuring the accuracy and stability of the measurement. Non-contact measurement method is adopted, and the operation is safe and simple. It can be connected to industrial control devices, data loggers, oscilloscopes, high-precision digital multimeters and other equipment.
