JRF333 Rogowski Coil Current Measurement Sensor
JRF333
Application:
Incorporated into applications where it is necessary that the sensor be capable of responding to a wide operating current range, a wide frequency range and/ or is exposed to harsh operating conditions.
Features:
- Single loop primary, capable of accommodating a range of primary conductor sizes.
- Characterized by high sensitivity, accuracy, linearity, minimum phase shift.
- Suitable for harsh operating environments (temperature, humidity, EMI).
