DESCRIPTION
Hawkeye DC Sensors provide accurate load level monitoring of DC current loads. The
H970 combines a Hall Effect sensor with proven transducer circuitry. Slide-switch
selectable amperage ranges and field selectable mA and VDC outputs maximize
flexibility. The H971 uses Pulse Reset Technology™ with field proven circuitry to
provide a superior solution for DC applications with minimal risk of permanent
magnetization, ensuring longer life and better accuracy.
The H970 has low and high current options with slide switch selectable amperage
ranges and a choice of 0-5V, 0-10V, or 4-20mA outputs. The EA20 and the H971 have
4-20mA output only. The H971 also offers bidirectional sensing capability and a
user-adjustable span to allow greater application flexibility.
