Measuring transformer of direct and alternating currents, converting the signal value to a normalized analogue current signal of 4...20mA. The characteristics of these converters ensure high accuracy of temperature reading due to the 12-bit precision A/D converter. The device is similar in function and appearance to standard active measurement transformers, but is capable of measuring TRMS DC and AC current components. The transformer is powered by a 4-20mA current loop and therefore does not require a direct power supply. It is the first loop-powered Hall transformer with 0.5% accuracy on the market.
