H721 SERIES & H921
VERIS INDUSTRIES
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 eld
setup of sensed amperage range with no need for jumpers.
APPLICATIONS
● Load trending
● Motor control
● Fan/Pump Status
EXAMPLE LINEAR OUTPUT
Scale software as shown

H721H C
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 retrot 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 eld-selec table ranges per unit...fewer versions to choose from, stock,
and install
● Removable mounting bracket for installation exibility
● Bracket on H921 can be installed in three dierent congurations...
added exibility
● 100% solid state, no moving parts to fail
● 5-year warranty
