ATR-120MV-11

Current Sensors Overview

The ATR-120MV-11 is a thin Rogowski coil current sensor manufactured by Aim Dynamics. It features an 11-inch diameter and supports a primary input range from 500 mA to 100 kA. The device outputs 120 mV per kA at 60 Hz and 100 mV per kA at 50 Hz. Coil resistance ranges between 70 and 900 Ω, with positioning error better than 1% of reading. It operates at a working voltage of 1000 V CAT III or 600 V CAT IV.

Current Sensors Feature Summary

• Thin profile design for flexible installation
• Built-in temperature compensation for accuracy
• High insulation voltage rating

Current Sensors Applications

• AC current measurement in industrial systems
• Power quality monitoring
• Electrical panel integration

Current Sensors Procurement Notes

Verify the specific model suffix against official Aim Dynamics documentation to confirm physical dimensions and electrical characteristics. Ensure compatibility with existing signal conditioning circuits. Confirm that the required current range aligns with the 500 mA to 100 kA specification. Check for any regional compliance requirements relevant to the application environment.

Current Sensors Selection Notes

Select this component when high-frequency AC current measurement is required without breaking the conductor. The thin form factor allows for installation in confined spaces where traditional transformers cannot fit. Consider the output sensitivity requirements relative to the downstream data acquisition system. Verify that the operating voltage class meets the safety standards of the installation site.

Current Sensors Part Context

This part belongs to the ATR-120MV series of thin Rogowski coils from Aim Dynamics. The series is characterized by its low profile and integrated temperature compensation. The 11-inch diameter variant provides a balance between aperture size and sensitivity for medium-to-high current applications.

Current Sensors Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Compatible alternatives must match the 120 mV/kA output sensitivity, 11-inch inner diameter, and similar resistance range. Verify interface compatibility with existing integrators before substitution.
