Aim Dynamics produces the AIMR-XXA-420-XD series a low amp current sensor. This unit is ideal for measuring amperages from 10A-200A where a Rogowski Coil with a 4-20mA output is required. Available for 1 or 3 phase power.
The AIMR series is an excellent choice for ground fault detection or measuring imbalances between phases using only one Rogowski coil. Alternatively the AIMR can be ordered with 3 Rogowski coils. The Rogowski coils can be one of 3 sizes: 5″ diameter, 8″ diameter or 12″ diameter. Custom sizes can also be requested. NO EXTERNAL POWER REQUIRED for the 4-20mA loop but rather receives its power from the loop (loop must be between 8-35 Vdc). Built in lights on the integrator box indicate if the proper voltage exists (and whether or not the loop circuit is complete). The integrator box can be mounted securely with screws to any stable surface.
