LWSR - Industrial current sensor
The LWSR series is used for DC, AC, or pulsed currents measurement with galvanic separation between the primary circuit and the secondary circuit.
LWSR sensors are designed with an aperture to insert the primary conductors.
The LWSR current sensors operate based on the closed-loop Hall effect principle. This technology ensures accurate and reliable current measurements in various applications where these sensors are utilized. LWSR sensors are suitable for industrial applications.
