In the realm of electrical engineering, the precision and reliability of current measurement are paramount. As a leading provider of advanced sensing solutions, EITAI Instrument specializes in a range of current sensors that cater to diverse applications across various industries. We’ll delve into the intricacies and applications of three types of current sensors that we offer: Hall Effect Current Sensors, Current Transformers (CTs), and Rogowski Coils. Discover how these sensors contribute to efficient energy management, motor control, and used in ours EITAI5000 power quality analyzer.

Hall Effect Current Sensors

Function:

Hall effect current sensors utilize the Hall effect phenomenon to measure current without making direct electrical contact with the conductor. They are ideal for applications where isolation between the measured circuit and the sensor is necessary.

Products:

EITAI007AD Series AC/DC Clamp Current Sensor

Applications:

- Motor Control: Used in the control of electric motors for precise current monitoring, which is essential for efficiency and preventing damage.

- Power Electronics: Integral in power electronic systems for current limiting and protection against overcurrent conditions.

- Energy Management: Assist in monitoring energy consumption in buildings and industrial settings for better resource management.

Advantages:

- Non-intrusive measurement

- Galvanic isolation

- Wide frequency range

- Compact size

Current Transformers (CTs)

Function:

Current transformers are designed to step down high currents to a lower, more measurable value while maintaining the waveform of the current. They are commonly used in high voltage and current applications.

EITAI002F Rogowski Flexible Coil Current Sensor

Applications:

- Power Quality Analysis: Monitor power quality issues such as harmonics and transients in electrical systems.

- High Frequency Current Measurement: Ideal for applications where high bandwidth and accuracy are required, such as in switch-mode power supplies.

- Energy Harvesting: Used in systems that convert waste heat or mechanical vibrations into electrical power.

Advantages:

- Wide bandwidth and frequency response

- No magnetic saturation

- Lightweight and flexible design

- Suitable for both AC and DC measurements
