Open Loop Hall Effect Current Transducers

Posted on 25 April 2019

              Open loop transducers use the simplest implementation of the Hall effect. They provide the smallest, lightest, and most cost effective current measurement solution while also having very low power consumption. Construction and principle of operation A current carrying conductor creates a magnetic field. This field is concentrated by [...]

Characteristics of Closed Loop Current Transducers

Posted on 19 April 2019

              Advantages and limitations Closed loop transducers are capable of measuring DC, AC and complex current waveforms while ensuring galvanic isolation. The advantages of this design include high accuracy and linearity, low gain drift, wide bandwidth, and fast response time. Another advantage is an output current signal that is [...]

Handling Core Losses of Open Loop Transducers

Posted on 17 April 2019

              Causes of Core Losses in Open Loop Transducers The magnetic material and core design of a transducer, as well as the current amplitude versus frequency spectra, determine the level of core losses: • eddy current losses are proportional to the square of three different parameters: the peak flux [...]
