The magnetic field sensors are based on the magnetoresistive effect. Hence they are replaced by magnetoresistive current sensors. Conventional current measurement systems therefore tend to be physically large and technically complex.Ĭonventional sensors are physically large and technically complex also they have disadvantages as stated above. ![]() The basic sensor requirements are galvanic isolation and a high bandwidth, usually from DC up to at least 100 kHz. The current signal must be fed into a computer in which sensors convert current into a proportional voltage with minimal influence on the measured circuit. Simply connecting an ammeter to an electrical circuit and reading out the value is no longer enough. ![]() ![]() The measurement of electric current strength is not always easy, especially when the measured signal requires further electronic conditioning.
