LEM LXSR Current Sensors
LEM LXSR Current Sensors are designed for precise electronic measurement of DC, AC, and pulse currents, spanning from 1.5A to 50A RMS nominal. This includes models at 6A, 15A, and 25A, all while ensuring galvanic isolation between the primary and secondary circuits. These LXSR sensors feature low offset drift and integrated primary conductors, ensuring stable and accurate performance across a wide operating temperature range of -40°C to +105°C. Additionally, the LXSR components provide reference access via an extra pin, enhancing the versatility in various applications.
The LXSR current transducers are fully compatible with the LTSR series, offering seamless integration and flexibility for system designers. Built for industrial applications, the LXSR sensors utilize closed-loop Hall-effect technology to deliver high-accuracy current measurements. These sensors provide performance comparable to Fluxgate technology while offering a more cost-effective solution for demanding sensing applications.
