What is a Hall current transmitter AC 0–20A to 4–20mA RS485?
A Hall current transmitter is a device that uses Hall effect sensing technology to measure AC current in the range of 0–20A and convert it into standardized output signals such as 4–20mA and RS485 (Modbus).
It provides electrically isolated, real-time current data for monitoring and control systems, making it suitable for industrial automation and data center power monitoring applications.
How does a Hall effect current transmitter work?
A Hall current transmitter detects the magnetic field generated by the AC current flowing through a conductor. The Hall sensor converts this magnetic field into a proportional electrical signal, which is then conditioned and output as 4–20mA or digital communication data via RS485.
This non-contact measurement method ensures high safety, isolation, and reliability.
What are the advantages of using a Hall current transmitter over traditional CT-based solutions?
Hall current transmitters offer several advantages:
These features make them ideal for modern, data-driven monitoring systems.
Where are Hall current transmitters commonly used?
Typical applications include:
