LEM is claiming “unparalleled levels of accuracy” for its latest current transducer: 0.6ppm linearity and 10ppm maximum electrical offset, according to the data sheet, although “in-house tests have shown that the sensor can achieve linearity below 0.5ppm and offset of +/-5ppm”. Called IN 200-S, the sensor is rated at up to ±200A (dc or ac(rms), 300A ...
