CASR Fluxgate Current Sensors

LEM USA offers compact fluxgate-based current transducers

Image of LEM USA CASR Fluxgate Current SensorsLEM USA CASR current sensors are tailored for the electronic measurement of DC, AC, and pulsed current with galvanic isolation between the primary and secondary circuits. This product family features compact fluxgate-based current transducers, single-supplied (+5 V), and boasts low offset and gain drift, with a measuring range extending up to three times Ipn, and is designed for PCB mounting. CASR sensors feature three primary pins, catering to small current measurements from 2 ARMS to 50 ARMS nominal. Operating on closed-loop fluxgate technology, the CASR series is predominantly engineered for industrial applications.
