Hall Split Core Current Sensors for Accurate and Non-Intrusive Current Measurement

In modern power monitoring systems, accurate current measurement is essential for energy management, industrial automation, and power electronics control. One increasingly popular solution is the hall split core Current Sensor, which provides reliable current measurement without interrupting the primary circuit.

What Are Split Core Current Sensors?

Split Core Current Sensors are designed with an opening magnetic core that allows the Sensor to be clamped around an existing conductor. Unlike traditional current Transformers that require disconnection of the cable during installation, split-core designs can be installed directly onto live wires.

This non-intrusive installation greatly simplifies maintenance and retrofitting in electrical systems such as power distribution panels, solar inverters, and industrial equipment.

Many split-core sensors use Hall effect technology, which measures the magnetic field generated by current flowing through a conductor. The sensor converts this magnetic field into an electrical signal proportional to the measured current. Hall-based sensors are capable of measuring AC, DC, and pulsed currents with high accuracy and electrical isolation.

Advantages of Hall Split Core Current Sensors

Hall-effect split-core sensors provide several advantages compared with traditional current measurement methods:

• Non-intrusive installation – clamp-on design avoids cutting or disconnecting cables

• AC and DC measurement capability

• Galvanic isolation between primary and measurement circuits

• Wide current measurement range

• Fast response and high linearity

Because of these benefits, they are widely used in energy monitoring, inverter systems, battery management systems, and industrial automation.

Alternative to LEM Split Core Current Sensors

Many engineers are familiar with products from LEM split core current sensor series, which are commonly used in power electronics and monitoring applications. However, as demand for cost-effective and flexible solutions increases, manufacturers are seeking alternative suppliers that can deliver similar performance with customizable specifications.

Ferrtx offers Hall split core current sensors designed for reliable current monitoring in industrial and energy applications. These sensors provide stable measurement performance while maintaining easy installation and compact design.

Applications

Typical applications include:

• Solar power systems

• Energy monitoring equipment

• Battery and UPS systems

• Industrial motor drives

• Smart grid and power distribution systems

By combining Hall-effect sensing technology with a convenient split-core structure, these sensors provide an efficient solution for modern current monitoring requirements.
