    Current Sensors

    Current Transducer

    Hawkeye H421 analog current transducers provide reliable load trending information for large motor loads (up to 2400 A), with a proportional 4 to 20 mA signal.

    Overview

    Hawkeye H421 analog current transducers provide reliable load trending information for large motor loads (up to 2400 A), with a proportional 4 to 20 mA signal. The H421 versions include a span potentiometer that allows each sensor to be calibrated for maximum resolution.
