A current sensor is a device that detects electric current (AC or DC) in a wire, and generates a signal proportional to it. The generated signal could be analog voltage or current or even digital output. It can be then utilized to display the measured current in an ammeter or can be stored for further analysis in a data acquisition system or can be utilized for control purpose. You can buy current sensors or current transducers from us. The current measurement or current sensing is an essential part in our day to day life and are available at quite competitive price through robomart.
