80mm Loop, Split Rogowski Coil Current Sensor Application:
Incorporated into products used for electric power measurement, electric power quality monitoring, Supervisory Control and Data Acquisition (SCADA). The Rogowski Coil current sensor is ideal for current measurement applications that require a wide AC current input range and a wide frequency response range. Suitable for relatively small primary conductors, the mini-loop split-core design permits the installation of the sensor without disconnecting the primary conductor. These sensors offer exceptional accuracy in harsh environmental operating conditions. Features:
- Split-core loop design, capable of accommodating a range of primary conductor sizes.
- Open secondary does not present danger to user from stored core energy.
- Characterized by high sensitivity, accuracy, linearity, minimum phase shift.
- Suitable for harsh operating environments (temperature, humidity, EMI).
