The
operation principle of the Hall sensor is based on the
conversion of the induction of the constant or alternating
magnetic field into the voltage proportional to it. The sensor
ensures high sensitivity to the magnetic field.

CURRENT
DETECTOR BASED ON THE HALL CONVERTER
The current detector is designed
for measurement of alternating and direct currents; obtaining
a feedback signal in systems of automatic control of parameters
of technical systems; application in systems of control
of electricity consumption and account of electric energy,
e.g. in electricity meters.
The main element of the detector is a highly sensitive
thermostable Hall converter based on gallium arsenide,
whose output signal is proportional to the current measured.

ROTATION
FRECUENCY DETECTOR
The
rotation frequency detector is designed for measuring
the instantaneous frequency (or speed) of rotation of
shafts, rotors of turbines and other rotating units and
mechanisms in automatic control systems. Its basic element
is a special Hall's converter, which produces a signal
proportional to the frequency of rotation.
