Current Sensors: 4-20mA
Analog Output
Load Trending With 4-20mA Output
DESCRIPTION
The Hawkeye 721LC, 721HC, and 921 provide accurate load trending information
with a proportional 4-20mA output signal. Preset slide-switches provide easy field
setup of sensed amperage range with no need for jumpers.
APPLICATIONS
●
Load trending
●
Motor control
●
Fan/Pump Status
FEATURES
●
Power the sensor, and receive the signal with only two wires...lower cabling
and commissioning costs than with traditional 3-wire sensors
●
Self-gripping split-core for fast retrofit installation...no need to remove
conductor (H921)
●
Economical solid-core features adjustable bracket for easy alignment (H721)
●
Factory calibrated switch-selectable ranges for high resolution and
installation ease
●
Three field-selectable ranges per unit...fewer versions to choose from, stock,
and install
●
Removable mounting bracket for installation flexibility
●
Bracket on H921 can be installed in three different configurations...
added flexibility
●
100% solid state, no moving parts to fail
●
5-year warranty
