    LEM ART-B22-D175/SP4 Split-Core Rogowski Coil Current Transducer

     

    LEM ART-B22-D175/SP4 Product Overview

    The ART-B22-D175/SP4 is a flexible, split-core Rogowski coil current transducer from LEM's ART series, designed for non-invasive AC current measurement with galvanic isolation between the primary circuit (power) and the secondary circuit (measurement) .

    This model features a 175mm aperture, a 4.5m output cable (SP4 suffix) , and provides a 22.5 mV/kA output voltage at 50Hz . It offers Class 0.5 accuracy according to IEC 61869-2, independent of primary conductor position . The sensor is self-powered and operates over a temperature range of -40°C to +80°C .

    LEM ART-B22-D175/SP4 Core Advantages

    Rogowski Coil Technology: No saturation effect — no upper current limit. A single sensor covers the entire 10A to 10,000A range without overload concerns .

    Perfect Loop Technology: Patented clasp design dramatically reduces positioning error (error due to conductor position within the aperture) and external conductor interference .

    Class 0.5 Accuracy: According to IEC 61869-2, accuracy is independent of primary conductor position .

    Thin, Flexible, Lightweight: 6.1mm coil diameter, flexible design for easy installation in tight spaces .

    Non-Intrusive Installation: Quick setup without interrupting power supply .

    Internal Shielding: Enhanced measurement accuracy at low primary currents .

    Wide Operating Temperature: -40°C to +80°C suitable for harsh environments .

    Extended Cable Length: SP4 suffix provides 4.5m output cable for flexible installation .

     

    Why Choose the ART-B22-D175/SP4?

    No Saturation, No Upper Current Limit: Unlike traditional current transformers, Rogowski coils do not saturate — the sensor can measure any primary current without limitation .

    Perfect Loop Technology: Dramatically reduces errors due to conductor positioning within the aperture and external conductor proximity .

    Class 0.5 Accuracy: Meets IEC 61869-2 standards regardless of primary conductor position .

    Self-Powered Operation: No external power supply required — simplifies system design and reduces installation costs .

    Quick and Easy Setup: Non-intrusive installation without power interruption .

    Large Current Range: One sensor covers 10A to 10,000A — wide dynamic range without overload concerns .

    1000V CAT III PD2 Insulation Rating: Safe for medium/low voltage substation applications .

    4.5m Cable Length: SP4 suffix provides extended cable length for flexible installation in larger or more complex setups .
