LOAD TRENDING WITH 4 TO 20 MA OUTPUT

DESCRIPTION

The Hawkeye 721LC, 721HC, and 921 provide accurate load trending
information with a proportional 4-20mA output signal. Preset slide­switches provide easy eld 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 design for fast retrot installation...no need to
remove conductor (H921)

• Economical solid-core features adjustable bracket for easy alignment
(H721 Series)

• Factory calibrated switch-selectable ranges for high resolution and
installation ease

• Three eld-selectable 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 dierent
congurations...added exibility

• 100% solid state, no moving parts to fail

• 5-year warranty
