Yokogawa Test & Measurement Releases CT1000S AC/DC Split Core Current Sensor

04/16/2025

Yokogawa Test & Measurement Corporation announces the release of the CT1000S AC/DC split core current sensor. The CT1000S combines the accuracy of Yokogawa’s conventional current sensors with the convenience of a clamp design, and features a high common mode rejection ratio (CMRR) and excellent frequency characteristics, even at measurement frequencies of 10 kHz or higher. As such, the CT1000S is an ideal solution for test applications that require wide-bandwidth, high-current measurement.

The rising importance of energy efficiency across all industries is driving demand for increasingly accurate power measurements in high-current applications such as electric vehicles, trains, and renewable energy systems. While Yokogawa’s conventional CT series current sensors can be used in combination with tools such as the company’s power analyzers to perform multichannel measurement of large AC/DC currents and provide valuable insights needed to meet efficiency targets, their installation and removal require the disconnection of wires. With its clamp design, the CT1000S is a convenient and highly precise wide-bandwidth, high-current measurement tool that eliminates the need for the disconnection of wires.
