DESCRIPTION
The KMZ52 is an extremely sensitive magnetic field
sensor, employing the magnetoresistive effect of thin-film
permalloy. The sensor contains two magnetoresistive
Wheatstone bridges physically offset from one another by
90 and integrated compensation and set/reset coils. The
integrated compensation coils allow magnetic field
measurement with current feedback loops to generate
outputs that are independent of drift in sensitivity. The
orientation of sensitivity may be set or changed (flipped) by
means of the integrated set/reset coils. A short current
pulse should be applied to the compensation coils to
recover (set) the sensor after exposure to strong disturbing
magnetic fields. A negative current pulse will reset the
sensor to reversed sensitivity. By use of periodically
alternated flipping pulses and a lock-in amplifier, the
output is made independent of sensor and amplifier offset.
