FRS Series Open-Loop Coreless Integral Sensors
LEM current sensors offer open-loop coreless integral technology for the electronic measurement of current up to 9,000 A
LEM FRS series current sensors provide precise electronic measurement of DC, AC, and pulsed currents while maintaining full galvanic isolation between primary and secondary circuits. Engineered to handle currents up to 9,000 A, this series offers flexibility with either a 4 mA to 20 mA current output or a 0 V to 5 V instantaneous voltage output. Each sensor incorporates a large 104 mm aperture to accommodate substantial conductors or busbars, making it well-suited for demanding installations. Built on LEM open-loop coreless integral (OLCI) technology, these coreless transducers deliver dependable, accurate performance across industrial, traction, and trackside environments, ensuring robust measurement capability even in challenging conditions.
