Current transducers are a subgroup of sensors and transducers that primarily function to convert current input into a proportional electrical output, often in the form of a voltage. This conversion allows for safe and accurate monitoring, control, and regulation of electrical power systems. They can measure both alternating current (AC) and direct current (DC), providing crucial data for several applications in a variety of industries. This adaptability to different current types makes them particularly versatile and valuable.
Specifically, current transducers are widely employed in power distribution systems, medical equipment, automotive electronics, and renewable energy sectors to name a few. Their main characteristics include high accuracy, wide operating temperature range, and superior isolation capabilities. As a result, they are essential in ensuring operational safety, enhancing system performance, and facilitating energy efficiency. The primary manufacturers of current transducers encompass several key industry players such as Honeywell, Eaton, TE Connectivity, Phoenix Contact, and LEM International.
