High precision current sensor CSA302-P042T01/SP2

High precision current sensor CSA302-P042T01/SP2

The CSA302-P042T01/SP2 is a current sensor that can measure DC, AC, pulsed, and various irregular waveform currents under the condition of complete isolation between the primary and secondary sides. It is mainly used in fields that require high accuracy, such as metrological verification and calibration, as well as in fields that demand high sensitivity, stability, and reliability, such as power quality analysis, power analyzers, medical equipment, aerospace, and naval vessels. The sensor features high precision (50ppm), excellent linearity (5ppm), excellent temperature drift (1ppm/K), and a response time of less than 1 microsecond.

    Applications

    Particle accelerators

    In particle accelerators, the CSA302-P042T01/SP2 is used to monitor and measure the current in magnet power supply circuits that generate guiding and focusing magnetic fields for particle beams. The sensor accurately captures the high-current signals in real time, converting them into proportional voltage or low-current signals that can be acquired by the accelerator's control system. This enables precise adjustment and stabilization of magnet currents, ensuring the consistency of particle beam trajectories and energy levels. By detecting subtle current deviations that may affect beam quality, the sensor supports timely feedback control to maintain the accelerator's operational stability, which is essential for reliable particle acceleration and collision experiments in nuclear and particle physics research.

    Calibration

    The CSA302-P042T01/SP2 sensor with a precision of 50ppm is used in the calibration field as a high-precision reference standard. It is primarily employed to calibrate and verify the accuracy of other current measurement devices, such as ammeters, power analyzers, or current transformers. During the calibration process, the sensor is connected to a stable and controlled current source, and its output is compared with the readings of the device under calibration across multiple current levels within the 3000A range. Environmental factors like temperature and electromagnetic interference are strictly controlled to ensure the sensor's precision remains unaffected. This sensor’s high stability, low drift, and excellent linearity make it ideal for establishing traceability in calibration systems, ensuring that measurement results can be traced back to national or international measurement standards.
