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.

Kempston Controls stocks a select range of current transducers from market leading manufacturers such as Honeywell and Eatondesigned to suit many applications. Give our dedicated sales team a call on +44 (0) 1933 411411 or use the contact form above to discuss your current sensor requirements.
