Hall Sensors: These sensors utilize the Hall Effect to sense the flow of fluids. When a magnetic field is applied to a current carrying conductor, this force disturbs the current distribution, ...

Using the Hall effect for current measurement is inherently robust in high-power applications, ... the sensing element is positioned in parallel with the current flow (Fig. 2, again).

Hall-effect sensors are more suited to applications with frequencies higher than 1kHz. These include high-speed sensors for measuring revolutions per minute. Due to the lack of switch hysteresis, the ...

With options of a Hall effect sensor or optical sensor, the FT2 multi-range devices use a low inertia turbine supported on robust sapphire bearings housed in a chemically resistant body. Offering 9 ...

Hall effect sensors have been in use for over 50 years — and were even used by Sega in the Saturn 3D and Dreamcast’s controllers that debuted in the mid-’90s.

Advantages of the Proven AC field Hall Effect Measurement. For over 15 years, Japanese scientists and materials researchers have been using an AC Hall effect measurement method. Since the Hall voltage ...

The carrier-resolved photo-Hall effect. Courtesy: O Gunawan/IBM A new technique to extract information on the mobility of electrons and holes in semiconductors has unlocked a long-held secret in the ...

The spin Hall effect occurs when electrons with opposite spins go their separate ways in an electric field. The phenomenon is crucial to spin-based electronics, and its electrical signal has just ...

When a beam is reflected (or refracted) at optical interface or propagating through an inhomogeneous medium, photons with opposite spin angular momenta will separate with each other, resulting in ...
