Current Sensors

Vacuumschmelze (VAC) Current Sensors utilize amorphous field detector technology which makes the sensor more accurate and also improves linear performance with changes in temperature. The main function of VAC Current Sensors is measuring currents from DC up to high frequencies (approximately 200kHz).  These sensors contain a galvanic separation between the primary circuit and the output signal (according to EN 50178 or EN 61800) and typical currents range from a few amperes up to several hundred amperes full range. Some sensor types can measure more than 1000 ampere peak current. The accuracy of the VAC current sensors lies in the range of <1% of the nominal current. The VAC-invented measuring principle of the closed-loop sensor with magnetic probe as a zero field detector is distinguished by maximum precision of the current detection. The detected currents range from 6Arms to 700Arms.
