The H3A denotes a range of Low Noise SENIS Magnetic Field-to-Voltage Transducers with hybrid 3-axis Hall Probe.
The Hybrid Hall Probe integrates three high-resolution with good angular accuracy (orthogonality error < 2°) of the three measurement axis of the probe and a temperature sensor.
The Hall probe is connected with an electronic box (Module E in Fig. 1). The Module E provides biasing for the Hall probe and the application of the spinning-current technique, which very effectively cancels offset, low frequency noise and the planar Hall effect.
The additional conditioning of the Hall probe output signals in the electronic box includes Hall signal amplification, high linearization, compensation of the temperature variations, and limitation of the frequency bandwidth.
The outputs of the H3A Magnetic Transducers are available at the connector CoS of the Module E: these are high-level differential voltages proportional with each of the measured components of a magnetic flux density; and a ground-referred voltage proportional with the probe temperature.
