CT-4809 Current Transducers

The model CT-4809 is a Hall-effect current sensor with signal conditioning in a single compact package. Hall-effect current measurement is a non-contact technique that measures the magnetizing effects of current flowing in a conductor. Advantages of this technique include high electrical isolation between the measured conductor and transducer output, high over range capability and fast response to input changes. The loop-powered design simplifies installation by reducing instrument power and output signal connections to a simple 2-wire interface.
