The F1A denotes a range of SENIS Magnetic Field-to- Voltage Transducers with fully integrated 1-axis Hall Probe. It measures magnetic fields perpendicular to the probe plane.
The Hall Probe contains a CMOS integrated circuit, which incorporates a group of four Hall elements, biasing circuits, amplifiers, and a temperature sensor. The integrated Hall elements occupy very small area (0.4 x 0.04mm2), which provides very high spatial resolution of the probe.
The on-chip signal amplification provides high output signals of the Hall probe, which makes the transducer immune to electromagnetic disturbances.
The Hall probe is connected with an electronic box (Module E in Fig. 1). The Module E provides biasing for the Hall probe and additional conditioning of the Hall probe output signals: amplification, linearization, canceling offset, compensation of the temperature variations, and limitation of the frequency bandwidth.
The output of the Module E are high-level differential voltage proportional to the measured transverse (Y) component of a magnetic flux density and a ground-referred voltage proportional to the probe temperature.
