A current sensor is a device that detects and converts an electric current into a measurable output signal, typically a voltage, current, or digital signal. Current sensor is also called current transducer.Its operating principle depends on the technology used. Common methods include measuring the magnetic field around a conductor using a Hall-effect chip or a Rogowski coil, or measuring the small voltage drop across a precision shunt resistor inserted into the circuit.Tianrui has been a current transducer manufacturer for over 25 years and has extensive experience. It also accepts customization.
Product Features
1. Non-Intrusive and Intrusive Options: Many sensors (like Hall-effect or Rogowski coils) are non-intrusive, allowing for easy installation without breaking the circuit. Others, like shunt resistors, are intrusive but can offer high precision.
2. Wide Measurement Range and Bandwidth: They can measure everything from tiny DC leakage currents to massive AC surges, with some types offering very high frequency response for analyzing fast transients.
3. Versatile Outputs: Unlike traditional current transformers, they often provide DC voltage, analog, or even digital outputs, making them easy to interface with modern data acquisition systems, PLCs, and microcontrollers.
Common Applications
Current sensors are ubiquitous in modern electronics and power systems:
1. Motor Drives and Control: Monitoring phase currents for precise speed and torque control in industrial machinery and electric vehicles.
2. Overcurrent and Fault Protection: In battery management systems (BMS), solar inverters, and power supplies.
3. Power Monitoring: Enabling energy efficiency in smart appliances, data centers, and building automation systems.
