Abstract:
A device for measuring current magnitude in a conductor to an electrical device and for generating a signal comprising a series of pulses having a frequency, the frequency of the series of pulses responsive to the magnitude of current measured, the device comprising:a sensor magnetically linked with a power cable connected to the electrical device, said sensor producing an analog signal in response to the presence of a current within the power cable; a signal conditioner located proximate to said sensor and being electrically coupled to said sensor so as to receive said analog signal, said signal conditioner producing, in response to receiving said analog signal, a first signal representative of a magnitude of said current; and a converter for receiving and converting said first signal into an output signal comprising a series of pulses having a frequency, the frequency of the series of pulses being responsive to said magnitude of said current, wherein all of said sensor, said signal conditioner, and said converter are located in a single unitary package.
