4-20mA Output Current Transducers
4-20mA Output Current Transducers
Hawkeye x21/x21SP analog current transducers provide reliable load trending information for large motor loads (up to 2400 A), with a proportional 4 to 20 mA signal. Three devices are available, each with a different amperage range. The Hx21 versions include a span potentiometer that allows each sensor to be calibrated for maximum resolution. The Hx21SP versions are factory-calibrated at a range specified by the customer.
The Hawkeye 721LC, 721HC, and 921 provide accurate load trending information with a proportional 4-20mA output signal. Preset slideswitches provide easy field setup of sensed amperage range with no need for jumpers.
