Current Sensors
Current sensors detect the electric
current in a wire and generate an electrical signal that is proportional to
the current value that has been detected. The signal that has been generated
could be analogue voltage, current or a perhaps a digital output. This
generated signal can then be utilised to display the measured current in an
analogue or digital ammeter or utilised to control another circuit.
Current sensors (often called current transducers) are generally available in
either open-loop or closed-loop versions.
Open-loop
sensors measure AC and DC currents and provide an output voltage proportional
to the measured current without using a feedback control mechanism. The
preferred sensor of choice in battery-powered circuits due to its low power
consumption and physical size. Potential applications including variable speed drives,
UPS overcurrent protection and welding machines.
Closed-Loop
sensors depend on feedback control to provide an output that is proportional to
the current being measured. Sometimes called a Zero-Flux sensor, it features a
Hall-Effect sensor that feeds back an opposing current into its secondary coil.
Closed-loop sensors are often used when high accuracy is paramount.
